I could probably find a raft of examples for either side, so I really don't think it matters, in my opinion. Someone entering a market after the first is going to look at the competition and try improve and create something more unique, if they win it'll be because they actually made something that's significantly better. And generally that improve the is going to be feature/design based rather than stability/performance etc... I personally think first to market business can sometimes get a bit complacent, you always need to understand are people buying your product because it's the best, or simply because it's the only one. If it's the latter then you need to constantly innovate and improve, or someone else will. The advantage of second to market is, a lot of your market research is already done...
