That's because a lot of the back-end is still Windows 7(ish) and the new bit is the front end. Do you still have your old laptop? If you do, install a clean fresh Windows 8 Consumer Preview on it and give it a go, took about 30 mins top to install Windows 8 on this sh!tty creaking laptop.
Full screen apps and full screen IE10 FTW.
Won't take long to learn, bottom left and right corners and top left corner for different options, right click at the bottom of the screen for App menu, get to app settings from bottom right corner.
Not tried IE10 in the 'normal' version of Windows 8, but the Metro version is superb
