"Google announced last Friday that, in accordance to its policy of supporting a current browser and the immediate predecessor, its Google Apps productivity suite would drop support for Internet Explorer 8 once Windows 8 ships. Neither IE9 nor IE10 are available on XP. Adobe announced on the Photoshop Blog that the next version of Photoshop CS would support only Windows 7 and 8. The current version, CS6, is available for XP but, amusingly, not for Vista, which was its successor. This is a much-needed boost for Microsoft, which anxiously wants to put XP out to pasture after 11 years. Despite efforts to get rid of the old OS, XP still holds 43% of the market, according to the latest monthly data from Net Applications. Among Steam customers, Windows 7 has 70% market share, covering both 32-bit and 64-bit, while XP has 12%. That confirms what has been known for some time: consumers are adopting Windows 7 at a much faster rate than businesses. I know there is a whole economic argument to be had, and these numbers are not precise or scientific, but if XP really can be found in only 12% of households but 43% of businesses (or something close to that), then it really is time for the enterprise to stop dragging its tail."
