I really like Ars the way it is. That said, more in-depth articles, like the CISC vs RISC one, and more Linux and NT tweak guides would be very cool too. Scott made a good point a while back about not changing too much that I agree with. I would also like to see a comparison of the PIII, Athalon, and Mac G4, to see which one really is the best chip. Comparitive reviews on products with a single item to reference against.
Forums are excellent.
Mainpage layout could be improved but that is more cosmetic than anything else. Great job everyone.
