Own one of each, 1yr old toshiba and 1 mth old acer. Both great laptops, both good screens . Acer are slightly cheaper. Not had to use either of the technical support, so cannot comment on that. The Acer i have is now on special at click here absolute bargain for the spec (i paid more).
I bought two Acer products, both went wrong, support was useless, I have never used them again, although I must admit I was tempted to buy a system from them as it looked good value for money, spoke to my son who works in IT, they tried a Acer system on a trial basis, they binned it, he told me my first thoughts about Acer were true, "keep away from them"
For me, Toshiba wins out on all out quality, Acer come a very close second with out and out versatility. Tosh's tend to be built better whilst Acer's tend to have more features or the 'more for your money, effect'
