It depends on the manufacturer. HP will honour it for example. No clue on Acer.
Judging by some of the discussions you have on here I'd say it's unlikely it's small change for you

Is it just me or should "display model" always be read as customer returns that look good enough to describe as a display model. I mean if any of the thousands of display models being sold on the web as display models were real surely they would still have some manufacturers warranty?
