Dropbox does not have an official app for WP. They are currently using a mobile version of there site to deal with WP. The apps developed for iOS and Android are pretty nice.
I saw there is a Skype app is coming and as soon as it does I will delete Tango - but I am still waiting like everyone else for a very popular app. I just figured it would be out by now.
Log Me In is not just a remote desktop connection. I have all my machines set up with it and I can manage other users access to those machines through it. Other people who use Log Me In can give me permission on their machines as well. So what I use it for it involves a bunch of changes not just throwing an app on my phone. Again this is popular software that is available for other mobile OSs. LogMeIn has been talking about development for over a year with no publicly revealed progress. Might be a WP8 thing or possibly the WP market is not big enough yet.
The voice nav is the biggie. I am not paying for voice nav on a smartphone. It seems that the non-Nokia Windows Phones are the only major smartphones without free voice nav either built-in or developed by a big player in maps. MS should have been a little more thoughtful about ensuring that across carriers and manufacturers that the phones provide similar experiences; it seems logical that they would want customers to have the same bundle of stuff - not one customer getting a good version of the OS and apps and another getting a stripped down version. I have been looking for a free voice nav app and will keep trying until there is a solution or I decide to go another route with my phone (pun intended).
I appreciate the offer and I will hit you up if there is anything else I am looking for - besides MLB At Bat and Hulu+.
