My usage pattern now (all done on the MacBook currently except where noted) and where I see it going in this scenario:
- quick email - iPad
- longer email - desktop
- Web surfing - mostly iPad
- youtube/online videos - mostly iPad
- managing iTunes - desktop
- MS Word - desktop
- video editing - desktop
- ripping/burning - desktop
- photo editing - desktop
- managing photo library - desktop
- viewing photos - iPad
- quick web-based work in emergencies - iPad? Can it do this? Or desktop
- serious work - currently done mostly on work laptop - still done mostly on work laptop
I'd sell the Kindle if I read a complete book on the iPad and find it a pleasant experience, else I'd keep it.
Overall goal is to streamline gadget inventory where possible, and to improve my experience in the majority of areas while suffering the minimum amount of new headaches/pain points.
Thoughts?
My first thought is: wait until the HP Slate or other Windows 7 based tablets are released. If usability is bearable - and I understand that it might given that that touch function on Windows 7 is much more advanced than in previous Windows iterations - you could replace your desktop with the slate for almost all of the functions you listed.
