"The sticker on the front of the chassis is an indicator of the first area
of cost saving. The badge says Intel Celeron M inside, rather than Pentium
M. The difference between the two is that the former has half the Level 2
cache, 1MB, and does not feature SpeedStep power saving technology, which
powers down parts of the processor when it detects that it's not required.
This is probably the biggest drawback of the system as on the move the CPU
will be running at full pelt all the time - not great when the battery life
isn't outstanding in the first place. This is also why Intel doesn't afford
the Centrino branding to Celeron M powered machines, even if Wi-Fi is built
in, as it is here."
