One of the coolest looking things in the new Windows Phone 7 "Mango" release (see all the coverage you can handle at WPCentral) is Microsoft's Bing Vision. It's essentially a Google Goggles clone (great artists copy/borrow/steal and all that), but the UI is really cool. Your search categories are visible while the camera is running, looking fancy and nice as a semi-transparent overlay while you're capturing the content you want to scan. Of course, WP7's Metro UI and its typographic look is in full force here as well.
As for functionality, Bing Vision doesn't look like it does anything out of the ordinary. No solving Sudoku puzzles, no translation built in, and the jury is still out about how it handles business cards. But that's not what people will think when they see it. I'm one of those "function trumps form" kind of guys, but the mobile market is growing like wildfire, and maybe it's time for Google to step up and revamp the UI and visual style of some of their apps so they look as good as they perform.
I use Google Goggles a lot, mostly because I'm a geek who loves to play with cutting edge tech, and I've went "all-in" with Googles apps and services. It works great, but visual appeal is lacking compared to the competition. See for yourself -- there's a video after the break.
