The only time I'd noticed a difference with not having Flash player is that there are a small handful of older websites no longer function -- and some of these these are so old that beside the Flash content no longer working, the formatting within HTML wouldn't work in web browsers newer than IE6.

>Just uninstall it, I doubt you will ever notice. I have never had it installed on my machine. It's pretty "old" technology. For instance iPhones have never supported Flash.
