I have found this with a tad more info about Windows 7 Starter/Netbook edition
Windows 7 Starter edition explained - Crave at CNET UK that might help. Seems info is very sparse. I would wait till someone reviews before I commited. Note the limit on running three applications at once. Email, browser and one office application will be typical. Could be a tad tedious opening and closing apps.
I have just upgraded one laptop to Windows 7 Ultimate to play with. Good news is that it so far it has freed up several gigs of diskspace that Vista was hogging, time alone will tell if it uses them up again. My daughter is the Vista fan and so she is going to roadtest it for me.
