i agree with a.p.r.i.l. you dont need a laptop yet. Its just high school. unless you need it for porn or something. HAHAH
but yer high school. its not much. i dont even have a laptop and we only have 1 computer, it works well. The only thing u need a computer for is Soompi and Homework. You don't even need to do so much research by computer anyway esp at high school
but anyway answering your question, from my experience, toshibas get really hot, vaios crash, asus is a relativly new brand to the laptop world, but it has its good points, i heard its pretty good and the price range is nice too . Um, acer, i think it looks very durable.
It depends on what you're looking for, like for example you want it to look nice, and okayish price, Macs can do that, but the prices are rather high right now. and like they die earlier. -No battery replacement
HP, looks good alot of people have it. They have good desktop replacements too. If you want portability, get those EE pcs, by asus and stuff, theres other ultra portable ones on the market as well. But i really don't like the interface. It depends on your style and wants. You should check out
