What PC? (April '01)
Weighing 3.2kg, the aptly named Rock was the heaviest machine
on test. However, this isnít backbreaking stuff and you get
the features to justify the size. Rock has earned a name in
the market for making well-specified portables at a good price,
and the Sigma continues this tradition.
The main reason for the extra size is the display, which
at14.1in is easily the biggest here. The size isnít immediately
noticeable: the casing in minimal and there is only a thin
silver border around the edges. The Sigma has the feel of
a functional all-rounder rather than the slinky refinement
of the Asus Hi-Grade.
The slightly bigger case is put to good use. It conceals
powerful components, most noticeably an 800MHz Pentium III
processor. With a generous 128 MB of RAM this makes for a
very fast PC- it scored 136 in our SYSmark test. However,
the Sigma uses a standard desktop processor that makes no
allowance for the limited power supply of a notebook, so you
can expect its Lithium Ion battery to last about half an hour
or less than the two and a half hours of the Hi-Grade. It
has a 14Gb hard disk- the second biggest in this test.
You donít really buy a notebook for graphics performance,
but the Sigmaís 8Mb ATI Rage Pro does a better job than most.
Thereís also an s-video output.
As with the Hi-Grade, the 8-speed DVD drive, stereo speakers
and huge display make the Sigma especially suited to movies
on the go. Work will be just as pleasant thanks to its extra-responsive
keyboard and smooth trackpad.
In terms of expansion, the machine has all of the standard
ports, including PC Card slots and a single USB socket. Thereís
also an interface for a docking station, and an IrDa infrared
