I've got a Transcend 32GB SSD in mine, and yes, the performance is great. Then again, the primary motivation behind my SSD purchase was that the original drive was dying (throwing lots of bad sector errors). I haven't really tweaked anything, just installed Win7 Home Premium and let it do whatever it wanted to the drive. I have a 1.1 with 2GB RAM. My drive scores a 5.9 in WEI. The whole system is faster than the netbooks I've had, and with a fresh battery, I can get close to 4 hours of run time. Considering the limit on drive sizes that can be put in these things anyway, I think an SSD is a great choice.
