I finished revamping my computer. I installed my upgrade to Windows 7. The actual installing Windows 7 stuff is simple, start it up, step away from the computer for 15 minutes, and it's done. The only thing that needed a driver was my laser printer and Windows opened up the page with the driver links in my web browser. I did update the Nvidia drivers myself, though if I didn't care about 3D performance I could have skipped that.
The pain is the anti-piracy for the upgrade. Since I didn't have XP on my machine (I switched to Windows 7 RC). I had to reinstall XP in order to upgrade to Win 7. Fortunately, XP turned out to be easy to install since the only driver I needed was the NIC driver. Even if I had XP installed, I'd have to reinstall it to my new drive since I wanted to put Windows 7 on the new drive. A PITA for someone like me with both a purchased copy of XP and a purchased upgrade of Windows 7. No snags in the process, just a pain as a legit customer to go through hoops, especially since the actual OS install was so smooth.
Having the system drive be an SSD is awesome. MS Word, Firefox, Excel, all open in about a second. I haven't timed the boot up time, but it is very fast. When the desktop appears, it's usable right away.
