wow, MS actually adding in WebGL to IE?? I'm surprised. I remember their program director basically saying they were not adding WebGL since you could use DX extensions (which sucked hard). Basically they didn't want people going open source over DirectX, only problem is they never developed WebDX.
Okay, so MS continues to play this perpetual 'catch-up' game with Chrome/Firefox functionality wise. I honestly would love to get off Chrome, because I always feel like every aspect of my privacy is being poked and prodded by Google.
My main problem with IE is that the number of browser extensions are slim to nil. They don't have a nice add-on store like Chrome has, no equivalent no-script add-on, I would also rather store my bookmarks (2000+) to SkyDrive instead of Google servers. But ultimately, I guess it really doesn't matter now, since both companies participate in PRISM anyways.
