Well, that's kind of the issue. I don't want to install all of the extra junk. Just a little of it. XP mode was the thing I was most concerned about not having.
That was the short answer. Here's the long answer, since you asked
I should start by saying that I was kind of in a weakened state when I decided to go Ultimate. Not by alcohol or lack of sleep, but by the process of selecting all of the components needed to build a PC for the first time. Felt like I was doing fairly well actually, making good decisions on price vs performance, until ....... the operating system.
Knew I wanted Windows 7. Had been leaning 95% toward Home Premium, except for two things.
(1) Was really concerned about not having XP mode (justified or not).
(2) Thought I stumbled onto a really good deal on Ultimate Upgrade that I didn't want to let slip away, so I jumped. Turns out, the deal is still there as we speak.... Guess I was a little quick on the trigger.
Regarding XP mode, I have some really old programs (mainly one) that I would like to run on this PC if I can, and I couldn't tell whether or not they would run without XP mode. And now since I'm getting Ultimate, guess maybe I'll consider using Bitlocker (but maybe not, since I already use TrueCrypt, when I need encryption for something).
What I didn't want if I could avoid it was a ton of menu options or features that aren't in Home Premium, that I'll never use, just to have one or two extra features. But knew that was a possiblity.
