I wonder which notebook i should choose...
Q40P is way lighter but performance-wise it is obviously slower than Q210
i want my notebook to be light
i am currently using LG R400H running C2D T5300, 2Gb 667MHz Ram and it is
2.2Kg
everytime i take my notebook out, it would be like killing me,
because I live in HongKong, I needa walk a lot...(most ppl in HongKong
can't
drive)
carrying a heavy notebook on the street all day long is not very wise...
but i as well dun want to have a computer which is too slow...
what's the point buying a computer which can't do things after all...

So, could any1 please kindly help sugest which to buy?
Thx a lot
