Asus EeeTop ET2410INTS-B024C £1100
Asus' offering isn't the sexiest PC but behind those '80s angles lie some test-topping specs. The 23.6in screen is highly responsive and with a quad-core CPU and respectable GeForce 540M graphics card, desktop software flies and the EeeTop has a decent stab at running games. Ignore the dull looks and this all-in-one gets it all right – and it'll be better still with Windows 8.
Packard Bell oneTwo L i5871 £950
Packard Bell's younger brother to the Acer Aspire line, doesn't feel cheap and with a responsive (and respectably bright) 23in touchscreen and a true quad-core CPU it's a great alternative if you're not a gamer. The oneTwo L i5871 is excellent in almost every way, especially if you pick it up at a bargain internet price.
HP Touchsmart 520-1080 £1100
HP has long been the leader in Windows touchscreen PCs and this Touchsmart also revels in Beats Audio speakers. It's a great design with top touch integration – HP's Magic Canvas overlay is the best of all the customised skins. The Touchsmart is let down by weak graphics and screen but it's definitely worth considering.
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.
Toshiba Qosmio DX730-102 £1000
At just 19cm thick, Toshiba's first all-in-one PC should look great on your desktop. And with a fine spec, including a Blu-ray drive, it could make a great work machine. The Qosmio DX730-102 is quiet and unobtrusive, but slightly let down by a lack of power, average screen and no discrete graphics card.
