I bought a TravelMate laptop from them, and after a while the screen would go black if it wasn't open at just the right angle or if you put pressure on certain parts of the laptop base (although this could make the screen normal again, too). Seemed like a loose connection or something. Sent it in under warranty and they decided it was the LCD screen, and so they replaced it and sent it back, claiming it "booted up normally," which was never the issue in the first place. Still had the same problem, sent it in again, and they replaced the motherboard. That fixed it. Also the touchpad sidebar scrolling feature doesn't work in a lot of applications. Besides that, I can't really think of anything else. Nothing really remarkable about it. I did get it at a decent price, though.
Based on my personal experience, I will look elsewhere for my products in the future, although I will not completely rule Acer out.
