All-day battery and ultra-lightweight design
Sony at its IFA keynote previewed an entirely new category of ultraportable. The VAIO X series will use a low-voltage Intel processor (either Atom or CULV) but will have a carbon fiber shell instead of aluminum or another bulkier material. Changing to the very light but stiff body gives it a record-setting weight of just 1.5 pounds, or half as much as most netbooks and ultraportables like the MacBook Air. It also slims the system down to just half an inch thick across its entire case.
In spite of its new dimensions and a larger than usual 11.1-inch screen, the X is known to have extremely long battery life and should last "all day and well into the night," though Sony won't say what this entails. Most other specs are vague, but 3G will be built-in.
Launch information for the system wasn't given at IFA as it remains a prototype, though a demo unit was running Windows 7 and implied that the system wouldn't ship any sooner than Windows 7's release in October. [via CrunchGear]
