Well, let us be honest, it seems that Ferrari is not the same depending on distibution area, for example, I saw some complain about heat, other about fan noise, for me heat is good, and fan is almost silent ( specially with daytime noise), if you got a problem then I strongly recommand sending it back, Acer need to know they have to provide all clients same specs, also I find people with 4002 complain more than people with 4005 (not sure really), anyway, maybe we should start a pool, and see what eveybody have in mind.
Sager, yes I wished if I can get one, for me Ferrari was the last piece of laptop in a client stock, I got it for good price, and it was deducted from my pay check, when I got it I felt luck, and let me tell you what I have used it for till now:
_I designed a full size Sign Board (Adobe Illustrator/Photoshop)
_Website design and Java programming (dreamweaver/Eclipse)
_Gamming (Rome Totalwar,HL2,The Day After)
Didn't fail me, BUT, I don't like the CD speed (ripping) and somtimes (and I think because I have allot of background apps) it have a playback lag (till I get the time to clean format it).
So don't hate it, just replace it with another Ferrari or Sager!
I hope I have ben of a help.
