You won't be able to find one to test drive. I found the Toshiba r10 and r15 to be comparable screen wise. The screen is "glassier" than the toshiba and it is real smooth to write on which I love. The performance is comparable to a standard desktop. My startup was extremely slow but once I removed Norton Antivirus it ran perfectly. I now use AVG for antivirus and Zone Alarm for firewall.
If you have any specific questions then let me know and I'll tell you what I can. I'm running the M275X which is 1.5 Ghz and 512 RAM with 60 GB harddrive.
