Never a Vaio, seen the state of gfx driver support. Want the best performance for money - meaning MSI, Asus for instance.
DIRT!
If a laptop does not have a proper dedicated memory and GPU it is a doorstop. I owned a C64 and Amiga not a Spectrum and Atari ST most of my life, this means graphics performance is important and I have no use for ASUS/ACER/MSI junk that can only surf the net or be used to play MP3s and flat refused to run even a 7 year old game like Battlefield 2 LOL
My work laptop actually runs rings round EVERY new laptop under £1000, it's a Dell Inspiron 9400 with a 2.23ghz C2D 64bit. But it's the GFX card (512mb Nvidia 7900GT) that makes it worth so much to me, I can actually play games in PS3 quality, unlike new machines stuck with browser based flash games. My other machine is a 2.23ghz Centrino D810, again with 128mb ATI X600 graphics, which still runs Need for Speed Most Wanted as well as the badly programmed Xbox360 port.
Sadly new laptops are marketed to nobs with 4gb ram and huge hard drives and a graphics solution that is inferior to what was on some Pentium 3 laptops last century and can not do transform and lighting in hardware in any way shape or form. Toys for little girls who spend all day on facecok.
VAIOs do have nice screens, and they used to have ATI dedicated GPUs, hopefully they still have something good given their pricing.
