The scratched area on the windows sticker is supposed to be there. It's the same on my 600m and on every other Dell laptop i've seen. So, essentially you got a perfect notebook for a scratch and dent price. Congrats!!
Yea the machine that can run FSX perfectly doesn't exist yet. Same thing happened when FS2004 came out. No one could run it on full perfectly but now a couple years later it runs smooth with full settings on just about any new machine.
