I tried to reply to the other Windows 7 discussion, but there was not button to post it.
I just bought a new computer with Windows 7, 64-bit version. Eclipse loaded without a single issue, and so far so good!!! No freezing, no delay in my writing. I'm waiting to receive the CoolGear USB-to-serial adapter to test my realtime. I'm using the Diamante, by the way, and that is working fine with Windows 7 and Eclipse.
The Windows 7 loads up and shuts down a whole lot faster than Vista. So far, it doesn't seem as quirky as Vista. It's pretty easy to navigate through the system. I'm going to keep my fingers crossed that this is a big improvement over Vista.
