Hardware Zone has Sony's ultra light VAIO VGN-TX37GP on hand in their latest review, which is a notebook you should consider if you're in the market for something light weight and portable. With portability top priority for the notebook, it's not the kind of machine to look at if your interested in processing power, though one of the benefits of a less powerful machine is longer battery life.
"However, despite having the dubious backing of Microsoft (Tablet PC anyone?), UMPCs are as yet relatively unproven in the marketplace. So for the frequent business traveler who needs a portable computer, thin and light notebooks are still the trusted option for now. For those looking to inspire gadget envy among their peers, they can turn to Sony's latest ultra portable notebook, the VAIO VGN-TX37GP to get their dose of glamour. This newly launched notebook bears the distinctive silver VAIO logo and weighs a mere 1.25kg inclusive of its battery and there's even an integrated DVD burner."
