My webapp: pik
getpik.com
getpik.com
I must admit that I found the heading "Do more on the web with pik." rather amusing.
Detecting the browser instead of the features is often bad practice: http://www.jibbering.com/faq/faq_notes/not_browser_detect.ht...
I'm whitelisting OS/Browser combos, and I haven't added linux yet.
According to jeresig, author of jQuery, one should not perform browser detection, instead you should use feature detection. Browser agent is not going to give you an accurate picture of what is supported because every browser likes to say they are mozilla/webkit/netscape/etc.
Works fine on Chrome 5.0.342.9 beta Ubuntu 10.04 AMD64.
