PS: I always buy my systems from Dell Outlet.
Currently I have a Precision m6600 with 2 HDs 320GB/7200RPM + 650GB/7200RPM. 8GB ram. 3.2GHZ etc...
I was on Phi Phi Island in Thailand, Laptop would not power up, called support they overnighted parts to BKK then had a tech fly BKK-HKT and take a ferry to Phi Phi, When he arrived he powered up PC and it worked, I felt like an idiot, He ended up replacing Motherboard etc anyway.
That is what I call an amazing warranty.
