The HTC Hero has been an object of lust for some time now for gadget enthusiasts. Even from the earliest days of leaked hardware shots and blurry demo videos of its UI, smartphone fans seemed to agree that the company had finally achieved what has been missing in the world of Android. Namely, a polished and attractive device — polished enough to go head-to-head with the iPhone — that kept its open source heart. So, here we are months later with an actual, bona fide Hero in our midst. Yes the reports were true, it is a beautiful device, both inside and out (though of course opinions differ on that chin). But does being a beautiful device mean Android is about to move to a bigger stage? Is HTC’s spit-shine enough to overcome some of the hurdles that have plagued the platform?

Industrial design
In terms of overall design and layout, the Hero is very much a product of evolution. Like its forebears the G1 (or Dream) and MyTouch (or Magic / Ion), the general stats like screen size, technology, and resolution, button placement, unit size and weight, and basic aesthetic are pure HTC. Like those previous devices, the Hero contains a smattering of hardware buttons on the base (or chin as some call it) of the phone, including a home, menu, back, send, end, and dedicated search key. The device also sports a trackball in this area, which shouldn’t surprise any Android aficionados.
Where the Hero breaks from convention, however, is in the overall look and feel of the phone. If the Dream and Magic felt plasticky and cheap (they did), the Hero is quite the opposite — it’s like a solid brick in your hand. The casing is made of a soft-touch material (Teflon on the white version to prevent dirt), and the shape of the device takes a much more severe, almost rectangular slant. The buttons along the bottom are small, evenly spaced ovals (save for the search and back key — we’ll get to that), the earpiece is covered in a stylish mesh, and the volume rocker on the side is a smooth, single button. The screen also uses a new oleophobic treatment (similar to the iPhone 3GS), and thankfully HTC has added a 3.5mm headphone jack to the top of the phone.

Since the announcement of Android Developer Challenge 2 in May, Android phones continue to be deployed in countries worldwide. Android phones are currently available in over 20 countries, with more on the way. As I’ve mentioned earlier, we’ll be including real-world users of these phones to help review and score your submissions. It is important to remember that your apps will be reviewed by judges around the world on actual devices; thus, be sure to make it extremely easy for users/judges to access your apps with minimum setup.

Some of you have been asking for clarifications on what we mean by “open only to applications that have not been published”. To be specific, applications that are available on Android Market before August 1, 2009 will not be eligible to participate in the contest. Users have already been providing comments for apps that are currently available on Android Market, so it wouldn’t make sense for them to “judge” the same apps again in this contest. In addition, apps that include or that are based on open source projects are fully welcomed, as long as the application itself is not on Android Market until August 1, 2009.

If you want to find out more details about ADC 2, you can find everything at the ADC 2 page along with the Terms and Conditions. For the moment, the most important thing to know is that ADC 2 submissions will be due August 31. I can’t wait to see what you all come up with this time.

Happy coding — and good luck!

Keep multiple applications open and move easily between them—email, maps, photos, websites, whatever. Pre thinks of your applications as activity cards, and lets you flip through them, move them around, or throw them away off screen.³

Things like text messages and calendar appointments appear as notifications at the bottom of the screen. You’ll know what’s going on without being completely interrupted or losing your train of thought.¹

Simply start typing to begin searching your contacts and applications. Pre begins with contacts and apps on the phone, and then offers to search Google, Google Maps, Wikipedia, or Twitter. With a fast browser at 3G speeds, you’ll find what you’re looking for in no time.⁴

Take great pictures with the built-in camera and flash. Watch a video on the vibrant color touchscreen. Buy songs from the Amazon MP3 store and listen using the built-in music player. Plus, use the Palm media sync feature to transfer your DRM-free iTunes music, videos, and photos to your Pre.⁶

Get applications by browsing the catalog on your Pre, and then download them over the air directly to your phone. Apps designed for the Palm webOS™ platform are integrated with other apps on the phone. Buy movie tickets, for example, and you can add the times right to your calendar.¹
