There is one model/version you want to stay away from. It has a buggy ethernet chip. It reliably, after X number of megabytes, goes strange and drops wireless connections.

At first they thought it was the driver. An updated driver was released. Them that are smart, figured out that what it did was overclock the cpu. As far as I can tell it didn't help. If you dig around in the Sevasoft forum there is much better info.

BTW: My GS is in the bin with all the other electronic bits I can't stand to toss, but should. It was replaced with a D-link part.
