Gamasutra - PC is not dead and mobile is shit (with Charts!).
Well the article title says it all: PC is not dead and mobile is shit.

Of course I make a certain type of game and the market is more geared up to sell PC copies of those, and indies releasing PC games on Steam certainly find they can do pretty well on there too compared to other platforms. Other developers are having great success on mobile - good for them. But I would urge caution in the mobile market. It's HUGELY over-saturated and hard to get noticed. I got my existing games ported to mobile as a low-risk approach, but there are teams of developers out there spending 6-12 months on mobile games and I personally think that's a recipe for disaster in most cases.

Looking at my numbers, perhaps I'd be best sticking to PC only? Putting all my energy into that and not buying expensive Macs (and constantly upgrading the OS and Xcode, and farting around with provisioning profiles and certificates) and not buying an ever growing army of mobile devices to test on. Most devs have a PC anyway, even if they just play games on it! For me anyway, PC is the clear winner.
