Hi, The OS doesn't make much of a difference to me although I do need to run WinXP to get VPN access into corporate as well as MS Project. Mostly I use the MBA for on the road VPN, email, browsing, note taking and light word processing/spreadsheets. I have a MBA R1 and would like to upgrade to the R2 for a few reasons, speed, I can't get the wifi working reliably on the R1, and the R1 gets hot especially when running Fusion. So, I'm really one the fence about buying another Apple, when the first one has its share of problems. Then I start thinking maybe a netbook is all I need and with the integrated 3G card, the Dell Mini is looking good. So, anyone look or try a X301 or even a netbook and have comments when compared to the MBA? Thanks. Regards-Michael G.
