I purchased one of these and it is very good. I cloned the 160 GB HDD to a 256 GB SSD and It makes Windows XP Blazing fast, But the battery is dead as a doornail.
I oughta do that with mine, because the hard drive in this makes the laptop rather painfully slow for a Core 2 Duo laptop. At least I have the restore discs to work with, which is always nice to have.
