This is what I'm afraid of the move from a "portable" device to a "mobile" device.

A nice finger friendly "mobile" UI is great on my phone which I can quickly use as an mp3 player, respond to a text message or two, read an email (not respond unless a short response is required), quickly browse the web.

What I bought my N800 for was use as an "portable" actually perhaps more accurately "ultra-portable" (when compared to netbooks) device/usage. I can use it to check/respond to emails that require longer responses, watch movies on the larger screen, review maintain spreadsheets/documents, sort through hundreds of photos / files on easily changeable sd cards, and much much more.

I already have a "mobile" device (phone) and a "portable" device (laptop). I was hoping for another toy to fill the gap between the two such as the current tablets.

It would be a very difficult decision to spend more money on a "mobile" device with only slight advantages despite the astronomically better hardware (from my humble point of view).
