I want a new laptop for school as my old one (samsung VM6000 series) is too big hefty and wouldn't work, so am going part exchange it for the QR20, but is this going to be a good investment? My Samsung has been very poor and i should have thought again before buying it, my Toshiba Satellite was better! Should i buy this? I'm a little worried that it'll be too big, but the carry handle will make it a lot easier to carry and it doesn't have as many extra ports and stuff that i hve on my samsung, but i don't use many of them anyway. And is 3kg too heavy for acrrying around school?? Thanks a lot J.Fitzgerald
