Not like it matters to any of the people on here -- I know how you guys are -- but the DS is, at the moment, a far superior system for games (and my system of choice) If you care to understand why I feel like I feel, keep reading. But you might want to get a snack first.
The games aren't ports of games we've all played to death by now; excepting Lumines, I haven't seen any original PSP games (maybe you guys have and can name a few?). Nintendo has been an innovation company forever -- the games are fun to play, and appeal to gamers of all ages. The "kiddy" argument is probably the most nonsensical I've ever heard; just because a game is content-safe for children doesn't mean that the game won't be deep enough to appeal to thinking players.
The wireless on the DS is surprisingly intuitive and fast, both on WiFi and with local wireless. I'm not sure how many PSP owners have wireless routers and have configured theirs for internet connectivity, but the "almost-a-cellphone" on-screen keyboard is annoying. Period. Whereas the PSP decided on a clunky-feeling interface to input text similar to a cell phone (multiple button presses), the DS gives something that ought to feel more familiar -- a keyboard. Tap the button, get a letter. It works. But I will say that the PSP has better options for network configuration; if you know about configuring a wireless network, you should know about the different protocols. The DS is locked to using WEP protocol or an open access point -- both of which are rather dangerous -- while the PSP is able to use many more (I don't have a list, I've only configured one a few times) protocols. Like I mentioned, though, the downside would be that the PSP, with all of its options, is counter-intuitive to actually use all of the protocols, because the keys take forever to input (think alphanumeric passwords upwards of 20 characters that are difficult to memorize on a phone with a dying battery).
Before I got a DS, I'd thought that touching was a gimmick. I still think it is, but it's a useful gimmick. It's extremely well-done in the games I've played (must...buy...Castlevania...) -- thus far, I've collected Meteos, Animal Crossing, Tony Hawk, and Mario Kart. Meteos and Animal Crossing are strict touch-screen games -- and they're comfortable. Mario Kart and Tony Hawk are mainly D-Pad/button games, though Tony Hawk has the "freak-out" (...) and Mario Kart's got custom emblems, which become many times easier to use when you can scribble.
The battery lives are about the same -- My DS battery will live for about 9 hours, the PSP for about 7-8. It's not really noticeable, and I actually prefer a particular feature of the PSP that was curiously not included with the DS, which is a battery meter. If you haven't played a DS...instead of knowing when your battery's going to die, it shuts off. Maybe there's something here that I'm not seeing (I have difficulty seeing some colors, so if the light changes, please tell me) -- but that can get awkward; however, the games are much better about my next point on the DS.
Memory. The DS uses cart saves. The PSP, already about 3 times the cost of a DS (or is it closer to 2-2 1/2 now?), uses memory cards, similar to a camera. For the extra money spent, you get [something like] a 32MB memory stick. But who, of the PSP owners here, is still using that stick? Did you upgrade your firmware yet? Because the upgrade itself takes about 15MB of that space as soon as it's downloaded. The DS doesn't make you worry about memory management, and it feels like it's meant to pick up, play a bit, and get on with your life.
Speaking of life, the DS is ready. The DS, like [nearly?] all Nintendo products, is extremely durable. Like the Gamecube, you can chuck the DS through a window into a bird's nest, watch it fall out of the tree, hit every branch, and pick it up and continue without even getting lapped (Mario Kart). I don't recommend it, of course, because it has an LCD screen, but the idea is that you can. You could continue using the system, and it would most likely play games as if nothing had happened at all. The PSP feels generally fragile. The old PSP commercial with the teens throwing it around to each other makes me laugh a little bit every time I see/think about it because a friend made a joke about someone dropping it and losing $300.
The DS is less expensive. I nearly said cheaper, but the system feels, like I just said, durable and ready-to-use. It's also, admit it or not, very powerful for being so compact. If you told me the PSP was more powerful, I'd probably believe you; it's a Sony product, and I expect power for the extra cost. But the DS remains competitive for a much, much lower price. On top of that, and this will probably go completely ignored, the DS has actually made sales. Over 10 million have been sold to customers worldwide (this is important -- often information in sales is released as "number of units sold to retailers"). [Here I would post PSP sales info, but it's hard to find. I'm curious about why.]
March 20, 2005. Metroid Prime: Hunters. Handheld + Free Wireless Internet + Hotspots wherever you can find a McDonald's + Shooter = Yes. If you read only this part of this omglong post, please -- reply to it. I'd like to know what the PSP people want to do when the mad popularity of Metroid goes online for free with control like a PC mouse.
Other stuff:
Music, Media*. Yes, the PSP can receive and play music from podcasts. I'm not a big music person, this doesn't appeal very much to me. Yes, the PSP has video releases practically daily; but these aren't DVDs. If you're buying a PSP only to view movies, you must be a drifter -- because the UMD movies will play in the PSP. That's all. Oh, and maybe a media center. So, instead of paying $100 to buy a portable DVD player that holds real DVDs, of which there are many more available than UMD movies, that you can share with friends who don't have a computer/have a computer that is so terrible that watching a movie would be unheard-of, you decide to pay the same price for a movie that you plan to watch once or twice by yourself, annoyed by people looking over your shoulder. Please.
Browser. Oh man, I wish the DS had a browser. I understand that Nintendo has gone to great lengths to protect children from being exposed to mature content or being taken advantage of over the internet (they might even be easily-identifiable; the DS has a built-in microphone, and will probably have [optional] VoIP with newer WiFi games). But I don't wish for the slow, ineffective PSP browser. If I'm at home, I'm going to use one of the computers. If I'm not at home, I'll probably just go home and use one of the computers, or go to a library. Total time would be about the same.
Cool factor. PSP has it here -- the system is sleek and beautiful. The DS is ugly. I'm OK with that. If looks are the deciding factor in your decision anyway, you should just buy a PSP. Ignore everything else. The gameplay isn't what matters at that point, it's just the eyecandy. Buy yourself an Xbox 360, too. Or ask your parents to. And pre-order the PS3. And buy a $600 video card, with all the prettiest features. Etc.
Wireless. DS has this. WiFi is fun. So what if I can't convince that hot asian chick to be my roommate in Animal Crossing? I can still school her at some Mario Kart (...ok, actually, I suck at Mario Kart.). After Mario Kart launched, almost immediately 48% of the people who has purchased the game were playing online. Worldwide. For free. Even Halo 2, after it's launch, only saw under 20% of the people who had purchased the game with unique IDs online. With the McDonald's hotspot deal in place, the DS's WiFi has nowhere to go but up for quite a few years. And...well, Pokemon. The game easily lends itself already (in single-player) to an MMO style of play; there's lots of grinding, lots of battling, and lots of trading. It doesn't really matter if you don't like Pokemon -- because when the games launch, and probably connect with the Revolution, online battling, trading, and chat are all on, and if you're not, you'll just get left out.
This reply constitutes "too long". If anyone responds to this and tells me they haven't read all of it, I'm actually OK with that. But keep in mind that if you respond with any harsh, idiot criticism and haven't read it, I'm going to take it for what it is -- not a damned thing.
And yes, I'm already prepared for the "omgyouwwrong!!!" replies. If you really want to flame me because my well-informed and calculated reply is "wrong", just go ahead and post it in this thread so you can get modded to BanLand. I don't have time for you in private.
* People act like the DS can't play any music -- it can, but it's a bit more difficult. Because the lines of piracy and legal homebrew activity are sometimes confusing, I'll just mention GBA carts, Flash ROMs, and MP3s. Figure out the rest. And yes, it's legal, though Nintendo may not be excited about it. The total cash spent on getting a DS and getting it to play music is only a little less than a PSP. I'm not doing it, because I already own an MP3-CD player, but I'm aware of it.
