I do indeed have an A2, and have had it for several months. On my old iPod, I wasn't a fan of the SQ of headphone out, so I used it primarily for movies. When I lost it, I almost bought another, but found Cowon, and was instantly converted. Beautiful picture quality, Video Dithering control (fixes granulated black pixels in dark videos.), 10hrs+ video life, I can practically watch an entire season of a given TV show before it lets up. The thing I do miss about iPod is the 80GB. Depending on how many movies you plan to put on there, you might find yourself yearning for space. However, the videos get copied on quickly, and you only need to plug in, copy&paste.
Definately recommended, I also put my favorite music on there, and the SQ is great with it. It'd most definitely not tiring for your hands, and I watch movies etc. Almost every night with it. All you have to do is prop it up sideways against a pillow, and you can watch videos through a 10 hour night. Great value, I got mine on newegg.com for 285 dollars. Creative Vision W was also considered, but the battery life is shorter, the screen is 3 inches smaller, it doesn't support text...the A2 is definitely my top choice. Go for it.
Also, I almost returned my A2 to await the Q5, but for one, that's gonna be a long wait more than likely, and the Q5 is going to be ridiculously expensive for it's Windows, Wi-Fi, text editor, all those gadgets of a PDA you'll likely never use. Just my two cents. (Q5 40GB will be around 500, 60GB around 550, if I remember correctly.)
