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.
