With its touch-friendly focus and new Metro UI, it's clear Windows 8 is Microsoft's play for the tablet market. But what's the appeal for traditional desktop users?
Market analysts IDC have issued a scathing assessment of the upcoming Windows 8's appeal to desktop PC upgraders, claiming the new OS "will be largely irrelevant to the users of traditional PCs, and we expect effectively no upgrade activity from Windows 7 to Windows 8 in that form factor,” according to a
report from US Microsoft watcher Mary Jo Foley. And even garnering significant traction in the tablet market may be beyond Microsoft, according to IDC, who call the company's prospects for tablet success in 2012 "disappointing".

The logic of the argument is that Windows 8's major appeal lies in its new tablet-specific touch features, such as the tiled Metro UI, and that users of the legacy PC desktop interface (which has come to define Windows versions up to the current Windows 7) won't perceive sufficient feature benefits in the new OS to justify upgrading from a Windows 7 install (which in some cases, especially in business and enterprise environments, might only have been recently implemented or rolled out).
Which is not to say that Windows 8 won't be a widely sold operating system, nor a successful release for Microsoft in other terms: as has been
pointed out, Windows 8 will be the default Microsoft OS in place on pretty much all non-Mac PCs shipped after its 2012 release, so a huge volume of installations is effectively guaranteed in the marketplace -- but the upgrade appeal to current Win 7 users (specifically those who aren't in the market for a new machine, that is) may well be questionable, especially if new desktop features or substantial performance benefits aren't revealed prior to launch (thought to be occurring towards the middle of next year).
