I would have gone with 7.5.3 or 6.0.7. I’m also fine with OS X and once they started shipping SSDs the virtual memory has been performant.

I miss having snappy menubar lists, at the Apple Store yesterday I noticed on the Neo that the transparencies and iconified menu items with shortcut glyphs are still perceptibly less buttery smooth.

As long as you ignore that whole part of the OS was still running 68K code on PPC Macs, it crashed like a drunk driving a semi truck without protected memory and the end user still had to fiddle with the amount of memory an app could use

Compared to Windows sure. Compared to linux, its incredibly bloated.
