I have around £ 750 to buy a desktop all-in-one, preferably with Windows 8 and touch screen. Advice?

PC all-in-one is almost a laptop on a stick, with a separate (preferably wireless) keyboard and mouse. Therefore, it should be relatively easy to design an all-in-one, especially considering the example of Apple iMac, which looks terrible. Unfortunately, it is very difficult to model with touchscreen style at attractive prices.

screens up to 17.4in in size, after which they become very difficult to manage. All-in-one above usually come in 20-inch screen sizes are the most common now 23in and 27 inches.

The first problem is that large flat screens are relatively expensive and large touchscreens are more expensive. This is especially true for capacitive touchscreens five points and 10 points for use with Microsoft Windows 8. Although Windows 8 can be used with any standard monitor five points is minimal tactile contact with a PC.

more designed for touchscreen Windows 7 had two points, as they only need a point of contact to slide the screen, and two trouble. (Two points touch still work with Windows 8.)

Paul Butler, an expert on monitors and sales manager specialist AOC monitor told me to go for a two-point touch screen with an optical or infrared for a 10 -point capacitive multi-touch screen and more than double the price of the screen. This helps to explain why its £ 750 could buy a good all-in-one PC with Windows 7, but has problems when it comes to Windows 8.

The situation is even worse if the style is an element, it can be the case of the PC all-in-one. These PCs are controlled (less cable tail) that can be used in a living room or bedroom furnished student rather than being relegated to a home office. But I think most of the good looking all-in-one are expensive, while the cheapest tend to be awkward if not downright ugly.

The all-in-one that is closer to hitting your specifications and budget is the HP TouchSmart PC Envy 23in (23-d010ea Research), which is the sale of PC World for £ 749 . It is great, but a little less annoying than the average, and has a good 10 points Multi-Touch Full HD screen with a resolution of 1920 x 1080 pixels.

What seems to be the same model with a touch-screen 23in and without Windows 8 is only $ 549.99. 10 points capacitive multi-touch seems to add £ 200 to the price.

TouchSmart PC features a 2.9GHz dual-core Intel Pentium G645 processor, 4GB memory, 500GB hard drive faster DVD-RW optical drive, keyboard and more wireless mouse. The memory can be expanded up to 16 GB 4 GB, but enough for normal use.

If you want to spend a little more, you can find the HP Envy 23in TouchSmart PC with Intel Core i3 or i5. They have better integrated graphics.

A lighter alternative, published on October 26, is the Asus ET2220 slightly smaller with 10 points 21.5in multi-touch full HD. This can be more or less, depending on the choice of the processor. The Asus model ET2220IUTI-B009K with Intel Pentium G645 2.9GHz, 4GB of memory, a 1TB hard drive, DVD burner, a TV tuner, card reader and costs £ 699.99 Amazon.co.uk, while model-B010K ET2220IUTI with a 3.3GHz Intel Core i3-3220 processor and 6GB of memory costs £ 799.99.
