While neo900 looks good, and I might even get one... I do think that it wouldn't pack enough punch to be doing a lot of the tasks that I'd imagine a computer doing.

To take around, as my phone, when I don't need to be doing anything too serious, then yeah - neo900 would be cool. I still love my old n900, and having a newer model of it would rock. If I want a computer in my pocket I think it falls short.
Some specs are already looking underpowered when compared to basic androids.
