New user interfaces certainly can be confusing, which is why many people struggle with Vista or Mac if they are used to XP.
But if your experience with Linux, especially Mint Linux or Ubuntu, you would be very surprised at the experience.
I suspect having to use Sudo for operations is the biggest problem facing newbies. I know it was for me. I hated it. I’ve since removed Ubuntu and am back with XP SP3. Enough with the typing commands and trying to figure out why what I typed wouldn’t work. Ridiculous.
