5 of the best touchscreen PCs

Acer Aspire Z5801 £1030
A true quad-core processor and a big 24in screen make the metallic Z5801 the closest you can get to an iMac without setting foot in an Apple Store. The Acer touchscreen all-in-one has noise and usability issues (it sits too high and is always tilting away) that count against it but it's still a lovely screen with performance to match.
