Oh I know that, but whilst the count for less than 50% of GDP they're also one of the biggest customer sectors for Microsoft, and one that is unlikely to dry up and disappear. They'll have a market there for as long as the market is there, and that's dependent on enterprise developers wanting to move development platforms to whatever the new hotness is. For consumers it's all a 'it depends'. It depends on whether it's good enough, rather than whether it does everything they could ever possibly need to.
