Hi Jim. I own a netbook (Asus eeepc 801).
This machine matches my Dell full size laptop for speed and memory, however the native screen resolution is non-standard. While this doesn't degrade display quality in my case, many graphics-intense applications require a higher setting.
When I want to use Smartview on my netbook, I can set graphics settings to emulate the higher resolution monitor, however I then have to use scroll keys to see parts of the display that are outside the viewable part of the screen. Even stuff like the bottom tool bar and mouse pointer can disappear out of view.
Apart from that, things like MS Office, etc. all seem to work fine. That said, when I'm on site with my imager and plan to work on things there, I take my Dell, not the netbook.
Cheers
