The virtual looping feature enables scrolling past the leftmost or rightmost homescreens with a quick bounce-to-the-opposite-end effect. While Fede implemented it this way instead of an endless scroll for technical reasons, I think it's visually a lot better and clearer, as you will still know when you've reached the end and won't feel lost in your own homescreen forest.
HTC most certainly brought the sexy, and those of us running alternate launchers (Launcher Pro, ADW, etc) or using phones without Sense, were getting kind of jealous. The solution came in the form of an app called Fancy Widget which mimicked the Sense widget almost to a tee, while adding a host of handy options:
Unsuprisingly, Fancy Widget got very popular, and HTC ended up sending Android Does, the widget's developer, a cease and desist order.
One of the reasons I love Android is because you can customize the heck out of your experience. Replacing the stock launcher with Launcher Pro is pretty much the first thing I do now when I get a new phone because of the innovations a hard-working, smart, and dedicated engineer (Fede) can bring to the table.
However, Launcher Pro is not too much different from the stock UI, outside of tweaks and other little but important things - same goes for ADW and other home replacements.
SwiftKey Keyboard has been in beta ever since its introduction to the Android Market a few months ago. Having tried Swype, I also jumped on SwiftKey to give it a fair shot and ended up sticking with it. Yes, it was that good.
SwiftKey is different from other keyboards because it uses predictive recognition based on both tons of statistical information and your own typing habits. In fact, you can make whole sentences without typing a single key and just picking default suggestions.
Today, Launcher Pro, one of the best homescreen replacements for Android, got a nice update, introducing a couple of new features and bug fixes. I replaced the bloated Sense UI on my EVO with Launcher Pro Plus about 2 weeks ago, and ever since then, half of my co-workers did the same, seeing what it can do.
The new update finally introduces a customizable number of icon columns and rows, which is no longer limited to 4 or 5.
