Having use Tiger for 5 days, I have to say I'm impressed, it's not as buggy as you would think.
I've had 1 kernel panick (1.5 hours after first use) while iTunes and Safari are open.
No freezes.
Dashboard works well enough that I use it often. (although the Calculator will still be running while your not using it, wasting RAM; similar with other gagets)
Safari seems MUCH faster, it's like I have broadband all over again. Except that it has some problems on webpages, like I can't view them. (see pic below)
Many apps are unstable under Tiger, for example IE (who uses that anyway), I can't use the hotmail with Mail hack, ect.
When I try to watch full screen movies, the tital bar at the top of the screen is still visible.
Of course, these are all the bad aspects of Tiger. 😉
It would take a much longer list to name all the good things. 😎
and sorry the pic is a pdf, Preview won't export to a jpg. 😡
