Using 0511 bios here and so far its running great although it does look like the battery is taking a hit.
I'm using nlite'd XP on mine and the one I bought for the missus is running the default linux OS. In fact she buggered her one up somehow and I ran her through the restore from the backup partition, and I was seriously impressed how quickly it did it - im sure it was a couple of mins, if that
Also found a great use for this at night, helping me do that boring journal research that i've been putting off for months.
sorry for the bad pic
