Really hope the browser get's updated soon, because it's gotten to the point where only a handful of website's(Not even this one,, or PlayStation Blog) work anywhere near properly on the PS3's browser.
Yeah, the Youtube logo doesn't display properly and you can't watch HQ or HD videos on the PS3's browser.
On the plus side Youtube XL(A version of Youtube for PS3 and Wii) no longer has lag and slowdown that can rival PES 2008 online, and actually works quite well now.
But i still prefer the normal version of Youtube because you can't view video comments on XL.
99% off stuff I use works just fine on PS3. I don't think I can think of a site that NEEDS flash 10.
Ps3's browser is like my phone, advertised as being flash enabled yet every site seems to require a flash upgrade.
