I had an Acer notebook which I used for abt 3 years, but after that, the LCD died. After 3 years, it was "almost" obsolete anyway. I fixed it for about $300, and it's still working now, 2 years later, at the hands of my employee.
I had an Acer 15" LCD monitor I bought 5 years ago (before LCDs became the norm) for abt $450 then. Other brands were selling for abt $600-750 at that time. It's still working today.
Slightly off topic: I had a Honda Civic (Genio) in 1993. For 5 years, it was a good and reliable car. I never needed any major overhauls. In 1996 I bought a Mercedes C180, and in 8 months, I had to change the gear coupling. The Mercedes people said "it was normal wear due to my driving conditions". It had less than 30,000 KM on it then. My Genio had over 90,000 and never experienced this prob....
Acer may not be the best quality, but it sure is hard to beat in terms of value for money.
