That's hard, both MP4s have touch-screens and both are nearly the same size, the iTouch is much more expensive but Apple creates more Music Players so more people trust Apple.
Samsung YP-P2
The good: The Samsung P2 offers fantastic audio quality and a large, brilliant touch screen. The interface is fun and customizable, and the player is packed with features including video playback, a great FM radio, support for subscription music and Datacasts, and a plethora of sound enhancement options.
The bad: The touch screen of the Samsung P2 is not always precise, and the lack of tactile controls may not appeal to all users. There's no memory expansion option, and it's pricey.
The bottom line: The Samsung YP-P2 is an excellent-sounding MP3 player that will appeal to those looking for a cool touch-screen interface and stereo Bluetooth capability.
Apple iTouch
When looking at the iPod touch, you have a choice: you can either see it as an evolutionary leap for iPod, or a slight downgrade from iPhone. You gain a thinner shell, up to 16GB of storage, but lose a bunch of apps, the phone, and some other surprising things. In our opinion, it's both the leap and the downgrade, and therein lies the rub.
Physically, it's almost more of an attention grabber than the iPhone, at about 2/3 the thickness and wearing the signature iPod chrome jacket. Yes, the back is more prone to scratching, but it's oh so shiny. Removing the recessed headphone jack was also a smart move, as you no longer need compatible headphones, or a silly adapter to make it work.
• Much of the iPhone experience remains intact: the wonderful multitouch navigation, the supreme Safari browser, the ease with which you can sync to iTunes, then grab and go without that annoying Eject delay. New minor features like adding a period by double tapping the space bar and bringing up the music HUD by double tapping the Home button are both welcome additions that make using the iPod touch even easier.
• The iTunes Wi-Fi Music Store is thrilling to use, and works as billed. Not only is it easy as hell to find a song, click its animated icon for a preview and download it, in seconds, to your iPod; it's also impressive how it syncs back to your computer's iTunes library without any weirdness. (Hey, as people who have lived through all of the Microsoft-PlaysForSure-compliant software, we are always impressed when DRM music apps work as billed.)
• What we haven't yet reported is that the battery life is ridiculously good, well over the 5 hours of video advertised by Apple. In a NYC-to-SF flight today, it refused to die, playing video almost constantly for 6 hours and 45 minutes. We had the Wi-Fi turned off, but if you're smart you would turn it off on planes too. At least until Virgin launches Wi-Fi in 2008.
There are, however, some issues with the thing. We have brought some up, but here they are, out in the open, for us to discuss:
• Our biggest complaint is that the touch's screen is not as good as the iPhone's screen. As Adrian has already mentioned, when you look directly at the screen while playing video, the deep blacks look strange and opalescent, almost like a film negative. We have tried this on three iPods and they all returned the same result. The only way to solve this problem, in my experience, is to tilt the touch away from you slightly, so that the top left corner is angled down. Not a fun way to watch video. The iPhone does not have this problem in any noticeable way.
• One of the quieter breakthroughs of the iPhone was the physical volume buttons on its side. We were hoping this was a sign that Apple had recognized the need for quick, no-look volume adjustments. With an iPhone, you can turn volume up or down without pulling it out of your pocket. We view the lack of physical volume buttons on the iPod touch as a step backwards.
• We found that there can be some lag when doing video-intensive activities. We were trying to find a single frame of a movie to show off, and we skipped forward and back so much that the thing eventually just froze up for a spell. After say 10 seconds, it was back in action, but everyone hates a freeze. The software can also experience crashes in the same way iPhone apps do: the app you're in closes out quickly, and you have to relaunch. Fairly painless, but potentially annoying.
• Old iPod video accessories don't work with the iPod touch. As we reported with the nano, the iPod touch doesn't support video through its headphone jack. All future video out will be through the 30-pin connection, but old third-party video products using the pin connector don't work either. While future products are on the way, anyone with old hardware is going to have to upgrade. On the bright side, component video out is now supported.
• No disk mode. We're not quite sure why this disappeared on the iPhone to begin with (cellphone data sensitivity, perhaps?), but its the same on the iPod touch and we don't like it one bit.
• Here are some less extreme gripes we'll just get off our chest: No video downloads in iTunes Wi-Fi Music Store, no wireless syncing to iTunes, no external speakers, dumbing down the calendar, and no Mail or Notes apps. This falls into the same category as our bitching about the lack of stereo Bluetooth A2DP on the iPhone: would be nice, might happen with a software update. Seriously, Steve, we're just planting the seed.
• So far, we've had no luck with AppTapp, but we don't think that it will be long before we can load third-party apps onto the touch, too.
The bottom line, if there is one, is that this will certainly be a great product for people who are unable or unwilling to sign up for AT&T. But spending $399 on the 16GB touch is not better than spending $399 on an 8GB iPhone. There are real reasons why the iPhone is a better iPod than the touch, especially now that both will have equal access to the iTunes Wi-Fi Music Store. Choosing the touch over the iPhone is like choosing a fully loaded Toyota Avalon over a Lexus ES.
