I used IBM, TOSHIBA, DELL, ACER before. From all these laptops, I think TOSHIBA is more reliable and cost effective. IBM too expensive and heavy, Acer not band in pirce but easy to broke, DELL is expensive but the quality is not bad. If you want to buy it in Montreal, you can consider TOSHIBA or DELL. I donot know what's the service of these two, it's another matter you need to care.
