Yes, if you later restored the image, it would be exactly the same as when you took the image. Should be no errors, activation issues, etc....because what you did was take a complete snapshot of the hard drive (registry, hidden files, and all). When you restore back to that image, it's as if you never did anything at all to it (nothing changed as far as XP is concerned).
Yeah, I'm planning on ordering that netbook in the next couple days, and it should be here within a week of ordering it. Yeah, I probably don't have the time either (school will keep me pretty busy), but I'm going to do it anyway. haha. I'm tired of carrying around my big, heavy Dell as you can see in
this topic. That's why I'm getting a netbook.
As for the battery life, even if 7 uses a smidgen more resources than XP, I don't think it will affect the battery life, and here's why. Windows 7 has great built in features that control performance and longevity. There are a lot more power options in 7 than there are in XP, such as "Dimmed display" which dims the display to a certain brightness after a specified amount of time. There a lot of other things that make it easier to save power or boost performance, if needed. So even if 7 does chug more juice than XP, if you have correct power settings, you should see almost the same battery life.
Yeah, Starter is pretty limited. You can't change the theme, background, colors, etc...without using a special third-party program. I tested in a virtual machine on my computer for a little while, but I didn't spend a whole lot of time with it, so I can't remember all that you can/can't do. It's exactly what it says it is: Starter. It's enough to get you on the internet, word process, etc....just be glad they didn't go through with that 3-open-program-limit they were going to put on it.
As for whether or not Starter is more efficient than the higher versions....well, it's kind of hard to say that it isn't. The features are so limited, you can't help but to think that it is using less resources than say Pro or Ultimate. But I mean, the only thing separating Starter from the other versions is the correct Product Key. If you went to Best Buy and a bought an Upgrade box (it's just an empty box with a product key inside), your Starter would magically change from Starter to whatever level you bought the Upgrade for (at least that's how it's supposed to work). And not to mention that every install disk has the stuff to be whatever version you want, it makes it all seem the same then.
So in this case as well, I don't think there will be that big of a difference in performance/longevity. It's hard to know without testing it, but my educated guess says that it won't.
I'm going to watch a couple more video reviews of that netbook today, see if my local Best Buy carries it, and if all goes well, it should be here by the end of next week (the 22nd). After my testing, I'll report back.
Any other questions you have, I'll be glad to answer.
