Got my S10 from Lenovo.com with 512MB and 80GB HD. After I added a few applications, I only had about 15 or 20GB left so it was already time for an upgrade. It took a while, but with help from Acronis Data Director I was able to upgrade to 320GB and still keep the same partitions that were on the 80GB, while expanding the C: drive. I'll be converting that to NTFS soon.
I also ordered the Bluetooth module and I'm waiting for that. I was a little disappointed to see that it wasn't included, even though it was in the user's manual and all the reviewers said it had it, as well as the sales people at CompUSA. I made sure that I went to CompUSA and told them to stop saying it has Bluetooth. I know, I didn't buy it there, but that's where I checked it out.
Anyway, I like it. I've got FarCry 2 running on it now.
