I've spent £130 on a 64GB Blackberry Playbook. Partially because it's QNX based, mostly because it's a ridiculously cheap price for a well built high quality bit of hardware that sadly didn't do that well. I can stick it in my bag, it's under a pound in weight (netbooks being around 3lb), and it will do most if not all of the portable things I want a device to do.
But, I have my netbook and my main laptop, and my main PC, and my home server, for all the other things.
