Some things I really miss and want them to steal and put into windows ( I know I can get some of these things from unix but the fact is I must run Windows most of the time ):
1. drive aliases. Basically the file system in Windows sucks. There are a ton of cool file systems in unix land but unless you want to really break tons of stuff AFAIK you are stuck with NTFS on Windows, no journaling FS in 7 like MS promised.
2. Real multitasking. The amount of things that make Windows unresponsive is mind boggling. Pop in a CD/DVD, try and print, explore the network, etc. Okay if you must, make ONE thing unresponsive, don't kill my whole OS trying to find all the printers on the network. I have 4 CPU's and 4GB of RAM etc and it's SLOW!!! WTF!
I never did like the Amiga GUI much honestly.
To the people who say that PC's at the time could brute force most of the hardware tricks the Amiga did, you are wrong, they couldn't, they sucked at it.

This post sounds like an old AI program I had for my Amiga called Ractor. It had a database of philosophical and other sayings and would remember everything you typed and feed it back into the dialog. -Jedon
