They make a widescreen version, check out the 4th post in this thread...and it says it can have either the x300, x600 or the x700...even comes with integrated ATI graphics as well, but I can't see any manufacturer using that option...
ahhh, I see now, there is a difference between the M622 and W622 Arima models, the M series uses the 27W Turion, and is a 4:3 screen, while the W series has the 35W Turion, and a widescreen...
oh, and to try and head off this question, both HP/Compaq and Gateway have used Arima models in the past, so that might be the U.S. brand that you see these lappys under...
