iPod Touch. It is very close right now.
Archos Android players don't have it, and swipe-to-unlock is an unnecessary extra step in an otherwise competent execution.
On the good side, the D3 has external buttons for power/hold (image below), and volume +/-, play/pause, and FFwd/Rev (right side). There are off-screen touch buttons for Back, Menu, and Home.
You can almost completely control media play without touching the screen. A single press of the PLAY button will usually start playing music without unlocking the screen. The power button will lock the touchscreen with one tap, turn the screen OFF with a quick double-tap, and bring up the power OFF option with a two second hold.
Internet: I had no trouble connecting to my home or work Wifi. The web browser works reasonably well, and multitouch zooming is greatly appreciated. There is a slight response delay after tapping on any on-screen link. It is as if the screen sensor has to think for a second before responding. Side-by-side with my iPod Touch the difference is notable. Scrolls are just a bit choppy on the D3 where they are smooth on the Touch. The D3 will show more info on a screen than the iPod Touch as the Touch adds an options bar on every web screen. The 800 x 480 screen is good, but not as crisp in detail as the Touch's 960 x 640 Retina display. Many web pages recognize the Touch and reformat to a Mobile view for it. The D3 usually gets a more typical PC page view on the same pages. Double-tap and finger-spead to zoom both work as expected. The web browser experience is better than on any lower resolution device, and better than any device without multitouch. It still isn't up to the standard set by Safari on an iPod Touch or iPhone, so Internet gets a B from me.
Apps: No app store on the D3. I've been able to side-load applications to my D3, and most have installed with no problem, the lack of an on-board market is a serious shortcoming Cowon needs to address. Out of the box the D3 includes your typical music, video, pictures, and radio media apps. You get email, web browser, YouTube, calculator (including simple and scientific versions), task manager, document (.txt) viewer, alarm clock, paint, voice recorder, calendar, contacts, comix, and twitter too. There are a few more apps on the Korean version of the D3 that disappeared when I installed the North American firmware. Until either Cowon or hackers get a Market app working on the D3 I have to give it a
Update 3/23/2011: Amazon.com has opened their Android Appstore now, and although the number of apps available is small you can expect it to grow exponentially. Easy to add their app to the D3.
