Sony :: May Be Swapping My Z90 For The HP 2530p

I love my VGN-Z90NS (weight, form factor, power, RAIDed drives), but the lack of virtualization support (that is, Sony's disabling of the VT-x feature in BIOS/EFI so you can't run 64-bit guests) is starting to cut into what I need to do for my day job.

I've been looking arund for something relatively equivalent and looked at a bunch of options which were close in terms of the spec of the Z as well as size and weight (under 4lbs). For those who care, those are:

Hewlett Packard 2530p
Lenovo Thinkpad X200
Lenovo Thinkpad X200s
Lenovo Thinkpad X301
Toshiba Portege R600

I love the size/weight of the R600, but I've had my share of underpowered notebooks (even though max memory is 5GB, not just 4GB) and it's not as easy to change out the hard drive (technically voids the warranty). I've configured various Lenovos, but I really want the optical drive internal which means the X200 series is out, and I didn't like the overall look of the X301, plus for that, I'd rather get the R600 which is smaller and lighter and better looking. Not all of the Lenovo laptops offer a 9-cell (if I need it; I have one for the Z), and the Toshiba does not. A latecomer to the game was the 2530p, which is under 4lbs, can go up to 8GB of memory (and being PC2-6400, it's cheaper).
