This is an Intel P7450 based machines. According to the Intel site here ...
...it says it doesn't support Intel Virtual Technology, (there's a Reg story on that and Vaio a few months back).
So it might be in for a struggle with XP emulation under Windows 7.
The Intel P84xx series chips are OK though but they're not in this part of the Vaio range and not at this price point. I found this last month when I looked at this machine for a friend. The Vaio experts at a flagship Sony Centre in central London weren't able to answer a question about whether it supported virtualisation or not. It took me a few seconds to find "no" on the Intel site.
So what of it? The intended user for this machine is a teacher and needs to run a lot of educational software, which is often built with not much more than 32 bit XP in mind, so decent XP emulation starts to matter. We had to say in this case she'd have a better chance of backwards compatibility with a Mac!
And as for the ones they've decked out in pink.... Ewwwww!
Value for money? Make up your own mind.
