Tried again on the Labor Day weekend to upgrade my Samsung Q1EX from Windows XP to Windows 7, using the Release Candidate (version 7100) that is publicly available. I was encouraged by reading posts in the Gottabemobile and UMPCPortal forums about the success of upgrading to Windows 7 for various other Q1 models.
No Go. Bottom line is that Samsung needs to step up with Drivers and Utilities to allow the Q1EX to work with Windows 7. Samsung, you have nice hardware. Please SUPPORT Windows 7 on the Q1EX!
