Windows 8 has now been previewed at a consumer trade fair. Apparently this is not a new Operating System but a modified Win 7 with an overlaid desktop similar to the Phone 7. It will be used on everything from tablets to TVs. As it's based on win 7 virus checking is still required, unlike the iPad and Android. The launch date has not been determined but early 2012 is mostly forecast. This is the same time HP will be debuting their new WebOs. The hardware requirement for the tablets is very specific which is upsetting some manufacturers including Acer, who are releasing three Ubuntu Netbooks in July. They are using their own modified version of last years Ubuntu which points to them having thought about this for a while, as Win 7 is very slow on a low powered Netbook.
