PLEASE do yourself a favor and don't get an Acer! We (the college I work for) purchased about 20 of them last summer and we've sent back no less than half of them for dead motherboards, failed HDDs, crappy WiFi cards w/ no range and can't connect to our network, etc... just bad.
We've been through so many that were supposed to be "good" that we consider it a craps shoot - we just buy the one w/ the best warranty and service so when they break we're not out for long. Gateway's been real good to us in this regard, good service and so far a pretty good product. Much improved over days of old, so our Help Desk guys tell me...
So I have a choice, I go with the flow and get a Gateway M-255E series laptop, or go "on my own" and get something else and fix it myself if/when it breaks (since I'm not going w/ the college standard). I'm thinking of just sucking it up and going w/ the Gateway. We've banged a bunch of them around and the build quality seems good.
Maybe it's because we're a college that we have good service, not sure. But.. YMMV of course!
