I hear the new ipad screen really "pops" - I am a part time photographer so to me, I would want the ipad2. But, hey, the ipad1 is just fine too.
As an aside, I just got a pair of Asus netbooks for my kids - they have HDMI outputs...all for 279 from bhphotovideo. Awesome is all I can say.
No matter your computing needs, there's a ipad/ipod/netbook/phone for you!
