Warning: this is a bit of a technical post, but not quite technical enough for the hardcore (as they're all likely to have seen it on The Register already), but may be useful to those looking at getting a laptop/netbook/ultrathin/ultraportable/handheld computer, or those who've already got one and wish to categorise it correctly.

Thanks to the wonderful world of computing, and now litigation, there are many different terms used for those super-small and lightweight "laptops" that you can fit in your handbag/coat pocket, but how do you know which one you've got or want?

Well thanks to The Register, this flow humorous flow diagram should answer all your questions and help you determine what type of little laptop you have.
