Do people buy tinybook are thay any good

It depends what you want to use the notebook/tinybook computer for.
If you want a light weight computer with a small screen and want to use it for e-mails and playing CDs and DVDs with a little word processing then it would be OK.
If you need a laptop with large screen and lots of disk space for graphics/photo editing, burning CDs and DVDs, editing movie and music files, downloading large movie and music files and using programs like desktop publishing, MOYB accounting package etc. then a tinybook would not be a suitable computer.

Well, customer reviews say tinybook is great. Read reviews here. Hope this helps...

Netbooks you mean? There are no good or bad things, just suitable and not suitable. If you have the cash and the need of a small, light, although not very powerful lappy, why not?
