We bought an Acer Aspire 5532 this past February, and LOVE it.
We had ONE issue with it - short term memory crapped out - but we sent it off to Acer, and had it back good as new within a week. It was covered under warranty (we didn't buy the extended warranty, this was just the one that came with the computer). We haven't had any other issues with it, and it works just fine. I use it for hours every day for school work (and surfing the web on AC and all that when I'm bored of homework... LOL). I'm perfectly pleased with it. I have two siblings that both got HP laptops a few years back, and both had many problems with them. My brother's crapped out altogether after about 2 years, and he's now got a Mac. My sister's has been repaired multiple times, and still has problems. I steered clear of the HP when we were hunting. Anyhow, I recommend Acer.
I like the computer. It works well. It has a nice keyboard (w/ a number pad, which was important to me). It's easy to use, and I'm very pleased with it.
