It's slightly harder to get a decent Toshiba in Canada. Even if you can, they're much more expensive. They're not bad for durability though, and aesthetic wise, they're half decent.
Acer is a brick. Not the greatest looking, but will last a while. It can take a bit of a beating... but not something I'd want to lug around. Usually cheap, but at the same time... hard to find a decent one sometimes because you only find the cheap old refurbished ones.
Lenovo is a brick with style. The acer is a gameboy, the lenovo is a PSP. Beat the shit out of this thing... it'll be moving. Quality is great, price is a little premium, but it lasts a shitlong time. However, specs are somewhat hard to get on this sometimes.
Sony is a hit or miss. Some are decent, some are cheap, some are bricks with style and some are good. However, there is a price premium... and remember, you're paying for aesthetics and not necessarily performance.
Compaq... shit. Go home.
Gateway... unknown. Basically a dell though. with less customization and less tech support.
Dell... hit or miss. Brick or decent. Easy to customize. But... quality again is hit or miss.
HP... aesthetics is decent. Build quality isn't bad. Parts wise they have slight issues, and the design sucks for ventilation.
Or something like that...
