So flash has always been a problem for me since its inception, in the beginning it was an ignorable plugin which wasn't an actual necessity. Then came portal owners, such as my ISP for example, that began creating their whole content with flash, so it was on a day like that that it ended up on my OS.
Flash was always sub par on anything not MS Windows, and in my case, that is not the OS I choose to use. Everything was tolerable until many sites also started to stream videos with flash, some is utter crap, but every now and then, it's nice to see something and flash is really resource intensive when dealing with things like this.
In addition to that, I've switched over to mostly being on a netbook when not at work, interestingly enough, flash is not friendly.
While doing some random blog reading, a project came to my attention, and it might be a good idea to keep an eye on, that would be lightspark
So there, I'll be checking on it every now and then, luckily, html5 and everything else that's been going on will catch up fast and deem flash unnecessary :-)
