I will have to take my hat of to you
I have put the challenge I described to 3 people who loved their tablets (2 Ipads and a cheap chinese thing running Android 2.1)
They all ended out agreeing that it was horses for courses.
Possible != better no mater how much you love your toy
I could probably do all the tasks with a Symbian phone as well, I would just prefer not to.
I could easily do them on My N900 but I wouldn't unless I had no other choice.
If you want the convenience of portability, you sacrifice size
If you want more convenience, lose the keyboard
If you want the same convenience with longer battery life, sacrifice processor power.
Everything is a balancing act which the user gets to choose.
At home or work, I want a desktop with a decent screen
In a different city or country) I want my netbook
On a plane, bus or train, I want my tablet or my Kindle
Walking around, My phone is more than adequate
Horses for Courses - unless you are involved in a religious argument
