Is that the question?
If so, except for gamers and programmers that use Virtual Machines I see little reason to go past 4GB.
I own the prior model dv6 and it was fine.
Costco sells an hp laptop dv6t that is 4 gb instead of 6 gb. It's selling for $699 which includes a wireless printer. Is this a good laptop. I am a teacher and need it for smartboard technology to project games on a smartboard.
