Locations is a real basic thing, geo tagging, take a photo add it and tell people that's where you are. Connected Media, is what it says, connect to a server and stream music, video and pictures to your phone. of course you need a DLNA enabled device and a wireless network connection. I get thrown out of the app as soon as I start it on the HD7.
Both apps adhere to the Metro design sensibility, and carry on a familiar HTC look for Windows Phone applications. Neither app is easily found in the Marketplace as yet, they are hidden, awaiting the "Mango update". If you are on Mango on an HTC device and want to give either app a try, you can download "Locations" Here, and "Connected Media" Here.
You can see the general look and feel, from HTC is carried over, I did a video of the HTC HUB early on in my pre Nodo look at Windows Phone.
HTC have been able to keep continuity with their apps, and considering their OEM knowledge, has kept the apps light and free. Most exciting is the ability for HTC in "Mango" to deeply integrate it's apps at a native, system level. Attentive Phone from HTC, is a really simple app, that allows some automation of actions via phone gestures,
HTC now have the ability to include simple apps like Attentive Phone into the OS, so rather than being in your apps list, it now appears in the settings menu, under system, not applications. It may seem a small thing, but it really shows the trust and strength of partnership of the OS maker and the OEM.
I expect to see more of this crossover happening as second generation Windows Phones hit the Market, OEM's that are in for the long haul are now starting to find a few Easter eggs.
