So can I use an SD card as a HDD?
You can't use it as a HDD but it will be usable for essentially anything. It's gonna be labled as a removable disk instead of hard drive though.
Also, I don't know what it is, but I just can't be super productive in Windows 8. I just "feel" like I'm going slower. I don't want to go back to Windows 7 just yet since I do love a lot of the new additions like snapping and such, but I just can't figure out why I don't feel productive in it.
If I had a laptop, I'd keep Windows 8 on there and Windows 7 for my desktop use to solve all my problems.\
Edit: Yeah, I think I'm gonna go back to Windows 7. I love Windows 8, but I really don't understand why I'm less productive in it. Maybe it's the fullscreen apps and desktop environment being kind of different from one another. I plan on buying one of those new Lenovo Ideapad Yoga 13's though, so I'll still be using Windows 8.
Edit 2: I wonder if there is a way to get those Win8 Style notifications in Windows 7...
