"It exactly does what is says... but nothing more"4.0 starson by rieln
Pros: Sleek, well designed, good screen, awesome screen (also outside), portable, high 'gadget' level, looks cool, feels cool, long battery duration (8 hours is easy)
Cons: Speed. It' s fast enough but heavy sites just won't be nice to work at. Try chrome-experiments, you see that that' s not what Google wants you to do ;)
Summary: It's a browser you can take with you and it's nothing more. For me it is a Pro, because I only want to have a browser. Not being annoyed with an underlying OS, it's very handy to just browse and work online. I get annoyed by a netbook running windows because it will need your attention now and then and after 3 months, just starting a browser takes more time than a compleet reboot of this system :)
If you think of that, it's a nice device which makes your online experience better than any tablet. But, nothing to see outside the browser. So decide for yourself.
