It is funny, the best laptop I ever had was an acer, I ran that sucker to death for 5 years and it is still being used by a friend of mine that I gave it to, right now I am on an HP, that has never had one problem and I have been running it going on 4 years and my wife's old Gateway that she ran for 4 years is still going strong, I sold it to a friend of mine and he loves it.. My wife has been running a Dell for going on 5 years now with never a problem. Of course Gateway is a company in name these days, and I believe that acer owns Gateway these days. I have not seen an emachine for years now, they were an acer company product, so don't really even know if they are making many computers these days.
So like I said, there are really not all that many computer manufactures these days, I believe Intel even has their mother boards sourced out to other companies.
