+1 for the general purpose PC. ive tried doing basic document editing on my acer a500 and tbh it just sucks. certainly when compared to the dual screen tower rig i have. Also it's just nicer to have a screen i dont have to hold up (call me lazy ) and a hard keyboard with *real* resistance to it means i can type faster than on the a500. Also the finger marks are F**King anonying to have to wipe off all the damn time.
Tablets and smartphones are good for care-free-computing (apologies to anyone who has used that prior to me) and those who dont want to have to care at all.
PC's may very well go back to being the domain of nerds and geeks only, which could one day see all the lusers on locked down devices with only well maintained PCs run by nerds on the net, or something in the same spirit as that.
i'll let your imaginations run wild with that last idea, i admit no real thoughtfulness in having just made it up...
