Well I guess my point is that I already have all of that. I have all my apps installed, I use the excellent Jablet.org for my IM. I have systems to open documents and whatnot, systems to sync my music etc. I had to learn though and it took me about 6 months to truly feel comfortable in this ecosystem.
I am a non partisan tech user, I own and use a macbook pro, ubuntu laptop and XP tablet, s60 symbian phones, N800, iPod 3G and 4G, ipaq winmo PDA. I am not loyal to a single way of doing things as there are always many ways. I just think the best approach would be to simplify how to get all the cool uses out of the tablet as well as keeping the device completely open to anything, but above all make it fun rather than frustrating to do stuff.
