Spinoff thread alert...!
Is this the model with a 4Gb primary SSD for the OS? Would be interested to hear what OS you use and how you get on with it... we've had a 901 model for a few years, running Windows XP but sadly it's now literally unusable as the number of Windows updates has completely filled the SSD. Tried installing a slipstreamed version, too, but that only bought about an extra year.
I'm guessing you're going to say Linux? Recently I fished it out for fun, and tried killing XP and installing Linux (not sure what flavour, and I'm not at all familiar with Linux) from the originally supplied CD; however by the time that had finished updating itself with several years'-worth of stuff, the problem was identical.
It's a total embuggerance that the machine has a 16Gb secondary SSD which you can't use for the OS, and which is almost empty :(
