"iPhone = my computer...Haven't bought new laptop since late 06"

This is my thought exactly - although for me my main computing platform is a poor man's iPhone, the iPod Touch (best £2 I ever spent) - and what I alluded to in my earlier JavaScript benchmarking post. It certainly beats a netbook.

Ironically, Tumblr is a bit over-zealous in its iPhone optimisation and I'll have to finish off formatting this post on my mac!
