Re: comparing x86 and powerpc laptops

I'd also add to check the display carefully.
Most new inexpensive PC laptops have an XGA display which is
1024x768. That may be fine. However you may want an
SXGA or SXGA+ if you intend to run at higher resolutions.
I've heard that most laptop displays only look really good
at a certain resolution. i.e. crisp, clear, no smearing etc.
I made a big mistake with my first laptop in that I didn't
check the display *and* the return policy. It seems Toshiba
and IBM will not exchange if you are not happy with the
computer. That was true a couple years ago anyway. My
Toshiba has a DSTN display which is only 800x600 and
too LCD like (leaves trails, i.e. too much persistance,
and has low contrast.) I hate to say good things about
Windows but Windows is OK on it. X is pretty lousy.
Lastly since I am thinking about my Toshiba. It has
a "blacklisted" BIOS so ACPI/APM doesn't work, and
an SiS graphics chip which is poorly supported.
One other comment about processor speed. It seems to make
the most difference to me only if you compile programs
frequently. A slower processor takes quite a bit longer.
For general use, surfing and typing processor speed does
not matter a lot, at least after after about 600Mhz IMHO.
Bottom line with the PC laptops: Check everything out before
you buy! I think the Apple laptops are probably better since
the hardware is more consistant (AFAIK).
I am getting a new PC laptop soon (already ordered). I'll
see if Debian works on it. :)
