Before anybody here recommends the Gimp as an alternative...yes, it's a well-done project, and yes, it admirably suits many people's needs.
But suggesting that the Gimp is a suitable alternative to Photoshop for a creative professional makes you sound as insanely stupid as that accountant who wonders why the company spends all that money on a huge financials package with a massive SQL backend when he could whip up something that works just as well in Excel with a few macros in an afternoon.
There is a serious lack of alternatives in this space; the monopoly Adobe enjoys is akin to AT&T before the breakup. Adobe clearly knows this, and this cloud bullshit is obviously an attempt to (continue to) cash in on said monopoly.
Most people I know are planning on camping out indefinitely on CS6 and hope something shakes free sooner rather than later. Long-shot dreams, such as Google buying Corel and turning PaintShop Pro into a Photoshop competitor, are being desperately wished for.
It's not pretty.
