I've been one of the few people that really hasn't felt too bad about Vista. It's been a fine operating system for me for the last 2 years almost. It's nothing special but I don't have a visceral reaction to it like others. However, there remain some little things that Microsoft does that just demonstrates the depth of their ignorance.
For example, lets say you get some of that super cheap ram on the market and you find yourself with 4gb in your fancy new PC/laptop. 32 bit systems only recognize up to about 3.25gb. I paid for 4gb though and I want to use it! Better take some time to get used to how they made the 64 bit version of Vista just different enough to really screw with you.
My aggravation today revolved around changing some settings in Outlook as I was moved to a new Exchange 2007 server. I went into the control panel looking for the Mail icon and it was nowhere to be found. I had to look several times to make sure. After a little Googling I discovered that Microsoft has decided to create a separate "32 bit control panel" within the regular control panel. Of course, I wasn't looking for that. Why oh why does that deserve a separate control panel.
Get a clue Microsoft!
