Am i right in thinking celeron d is for a desktop and celeron m stands for mobile i.e. a laptop?
Which is better a celeron d or a celeron m? im looking at a laptop which has a celeron d, and wondering why its not a celeron m!
its a 2.8ghz celeron d
256 ram
wireless enabled
dvd/cdrw drive
xp pro

all for £450 does that sound cheap? need one for uni and thought it was a decent price, brand new, toshiba a60 satellite, 12 months warranty does anyone know of anything better out there? was hoping for a dvd writer, but for around the same price i think id have to sacrifice a lot of performance any suggestions/comments?

The CMOS construction that is used in computer chips has a very flat speed/power characteristic so your D is probably running at a fraction of it's working speed to save battery power. And if you double the speed you cut your battery time in half.

im not too fussed about the speed of it really, obviously the faster the better, but my last lappy was a standard 1.2ghz celeron and that was fast enough, so you're saying it will do the job ok if i just leave it standard? or am i missing your point?

Well you really want the Ms for best battery life, all depends on what your laptop is for really.

i get you! yeah would probably prefer a better battery to a clock speed, as probably be using it on the train a lot but suppose for £450 cant complain for a 2.8ghz laptop, most ive seen cost more and are about 1.4-1.5ghz, they are cleron m's, but cant see it making that much difference, toshiba site says battery life is about 1.5 hours, i would have liked a bit more, my last was 2.5-3hrs, but might just look into buying another battery for it off ebay, then get the best of both worlds!
