SaaS
Anyone that buys Microsoft, Adobe, Apple, etc etc etc all buy subscriptions in one way or another. Sometimes that subscription is looser defined than others, but they're still in reality a subscrition: MS Office, Adobe CS, Apple Mac OS X, MS Windows, Salesforce.com, and the list goes on.
So, you buy an OS, or you buy a game, even! Even the game has a sequel - a new version, an update, whatever you want to call it. But you go out and buy it because it's new. Well that's exactly the market that SaaS caters for - you want the latest and greatest, but you don't need to go and get it yourself. It just kind of happens.
I'm not here to spark an argument, just showing that there is another side to the story, aside from MS being a money grabbing tight fisted swathe of <insert word>. That's my view of them, but I still see no issue per se with SaaS. I *DO* see the issue with games running on clouds without sufficient throughput across networks for the game to be sufficiently appealing to the users it is aimed at, but this is a discussion really for the software providers and the ISPs to have, and we know how that started, don't we BBC?
