I have the Virgin Mobile 3g usb adapter. It works on my Asus Netbook with Windows 7 starter (32 bit) edition. Remember 3g is like slow DSL - okay for general web surfing and email while on the road, but not for streaming movies. Virgin Mobile has not been without its share of problems - in March 2013 while travelling, with a layover in Houston Hobby, their service simply didn't work. I found this somewhat related headline:

I did not experience any problems with another trip in June 2013, with a layover in Phoenix International. I have the pay as you go plan so when I have to travel I order a month's worth of service - 500 megabytes for 30 days for $20. I chose 3g over 4g because 3g penetrates buildings better than 4g, and 3g is generally available in more places than 4g. Pay as you go may be a good option just to see if the service works dependably in the Aloha state.
