Windows 95 and XP were also big upgrades in my eyes, it took me a long time to get used to not using DOS!
That was what most put me off about Windows XP. I found it hard to conceive of an OS that didn't have DOS underlying it the same way Windows 95 and previous had.
I'm sure it's as much a quirk of my computing upbringing, I was using command prompts from probably the mid 80s, used to the level of control they gave me. I guess in part it's one of the reasons why I prefer Linux these days, I love to get my hands 'dirty' at the prompt, writing scripts to do stuff just like I used to write batch files and such like back in the day.
