Well it's a bit late, yeah, but I just finally did it so...
I sent my E1705 back to Dell today.. Paid $1685 for my 2ghz duo, 60gb 7200rpm, 7800 go, WUXGA screen, and a 4 year warranty.. Finally convinced myself I should wait a month or two for a better deal, or at least drop the warranty and maybe CPU down to 1.83 to more than cover the 7900 gs.
Losing the warranty won't make me feel half bad for looking into a merom chip later, and I guess I can always upgrade it if I get less ambitious. Anyway, another 7800 go(es) back to Dell!
The NEC DVD drive was loud as a mofo, too.. If that's quiet compared to Sonys, holy crap. VERY noticeable constant noise while watching a movie, really distracting.. hopefully that was actually defective..
Stinks waiting on credit for a Dell return, how long does that usually actually take? Their estimated 25 business days seems crazy!
