NEC calls the Versa S900 a sub-notebook with a 'thin, lightweight design', but this isn't the first impression it created with us. The Pentium M/Centrino-based S900's 28.4cm by 24.5cm footprint is certainly compact, but not to the extent you'd expect of a subnote. 'Small notebook' is nearer the mark. As for the thin and lightweight design, the S900 weighs 2.25kg, so it's not excessively heavy -- but again, when you consider that most true subnotebooks (or ultraportables) tip the scales between 1kg and 2kg, this is hardly groundbreaking. Nor is the system exactly thin: at 36mm (lid closed), it's the same girth as many a full-sized pre-Centrino notebook.
