Windows 8, yes or no?

Whats up peeps, I'm trying to decide whether or not to upgrade my windows 7 to windows 8. I installed 8 on a partition and it seems like a nice OS and seems to be quicker than 7, but I'd like some input from people because the only reason it seems to have been a "flop" is because no one was expecting a completely different UI. But as far as performance goes, it seems to be less of a resource hog, and generally better on battery life for laptops and it seems to start up/shutdown and wake up faster than windows 7.

Windows 8 has had some improvements made to the kernel, however, I believe the faster boot is due to the fact, that Windows 8 enters more of a sleep mode by default, rather than a complete shut down state (I may be wrong).

Windows 8 also has many features cut out, for instance I don't think you can play videos natively within Windows.

I don't like the fact, you need to create a Windows Live account to create a new user, I wonder where that information is being sent to..

I think the decision should be made based on what you use the PC for. If you use it mostly for social media browsing and appreciate an IPhone/IPad interface to navigate, then its worth trying.

But if you depend upon a stable desktop environment for productive work then I'd keep with Win7 which fully evolved to a perfect desktop experience, something which MS was known for and relied upon for but which is almost completely sacrificed in Win8.

I use my laptop for school and playing games on and the upgrade assistant said mostly all of my stuff will be fine after upgrading. Can anyone confirm if you get a decent amount of power efficiency out of it? Because after two years my battery is like at 55% of its original retention so if I could get like an extra half our or more out of the battery it'd be almost worth it. And like the Metro UI doesn't seem to bad- though I did see you can load the windows 7 shell into it and lose the metro all together

I'm not sure about the Power Efficiency with Windows 8, but to improve your battery life with Windows 7 you could change your Power Plan Options. It also depends upon what you doing, for example playing games is going to require much more power from your hardware.

I have been looking into the batteries, but cost a pretty penny from Dell, and I dunno how good the replacements are off ebay.. but back to W8 v. 7, does anyone else have any experience with the two side by side? It just seems like people were just shocked by the UI
