In a move that should be a wake-up call to the suits over at Microsoft, the company has revealed that it expects its Windows XP operating system to become even more popular in the coming fiscal year. XP, supposedly rendered obsolete by, ahem, Windows Vista, is expected to make up 22% of the total OS revenue. Vista clocks in 78% market share (no, they’re not still hawking Windows ME). This is up from the current 85% to 15% split. Could this mean that Vista is still far from being polished enough to actually compete with the company’s previous operating system? This is not a good sign at all.
