One of them is Leap, which lets you check out several home screens at once in a nifty grid. Besides Leap, I've noticed some new widgets and several minor improvements. For example, the browser now has a very nice way to copy and paste, as well as to check out dictionary definitions for a word.
The feature I liked the best, though, is the Friend Steam. It takes all the social elements you have stored for your contacts (for example Twitter and Facebook feeds) and displays them all in one place, lifestream-style. It's a really nice way to check what your phone friends (I refer to the contacts you have stored in your phone, which are often a different group from the contacts you have on social networks or e-mail) are up to.
I'll wrap up the HTC coverage from the Mobile World Congress in Barcelona with some images of HTC HD mini, which is somewhat less interesting than the Desire and the Legend simply because it's based on the soon-to-become obsolete Windows Mobile 6.5. Oddly enough, the Sense UI seems to run faster on the HD Mini than on both Androids, although the Mini boasts a 600 MHz CPU and is (in theory, at least) slower than the Desire. As you can see in the image below, it also has the advantage of looking good on the inside, which shows that HTC has started paying a lot of attention on the details.
Aluminum housings, pretty insides, is HTC treading in Apple's footsteps? Both the hardware and the software they've shown here at MWC are worthy of the comparison.
