1) File System - Looks like ZFS is the future - this sounds great! 2) GUI - I hope the rumors are true about a new UI in Leopard! This is very much needed. 3) Network File System - Should Apple just fix the bugs or adopt an entirely new network file system? 4) Kernel - I read a lot about how "bad" the OS X Darwin/Mach micro kernel is. Is it really a bad kernel or is it all just FUD? And if it is bad 1) what kernel should Apple use (Solaris, perhaps?), 2) should they reinvent the wheel and make it from scratch, 3) how dificult is it to give OS X a kernel-transplant? 5) What other major things need to be fixed in OS X to bring it up to perfection? What else is it lacking compared to the high-performance enterprise-ness it needs to compete with Linux / Windows in the enterprise world??? Is OS X riddled with problems, or does the above list pretty much cover it???
