But im using Acer Monitor, bt i never feel any problems with it, What kind of issues u faced with Acer products ???

The quality of the monitors are just very bad in my experience. Very dim even with the brightness turned up. I've used an Acer laptop and a monitor and both screens seemed to hurt my eyes after long use, which doesn't seem to happen with my Dell monitors. They also seem a bit cheap to the touch.. :3 personal preference of course.

Anyways back on topic. My problem with these all-in-ones are that if one component goes kaput and you are without computer. If the monitor fails then you have to use an external monitor and that defeats the purpose of an all-in-one. This would most likely be a home PC for internet surfing and streaming videos since there is no way it's going to be able to run games at decent settings.

I think all companies have in their range some bad and great devices. I have Acer laptop and to be honest it is great one, while before I was using Sony Vaio and it wasn't great, but at the moment the new L series is brilliant, it is all about the amount of cash you spend on your new laptop, monitor, etc...

but still it is more convenience to use laptop for TechSpy LOL
