First was Apple's iPhone App Store.  Then came word that T-Mobile was developing an App Store
whose launch might coincide with that of the Google Android-powered HTC
Dream phone, though it would serve up apps for all T-Mobile devices. 
And now it's Skymarket for Windows Mobile 7, the latest in platform-based software stores.

Unwired View
has published a Microsoft job listing detailing a Sr. Product Manager
position for Skymarket.  Skymarket is set to be the App Store for WinMo
7, a one-stop shopping outpost that MS hopes will be the place to go
for WM software starting sometime next year.  I'm not just making that
up - the place to go bit is straight from the job description:  

• Definition of the product offering, pricing, business model and
  policies that will make the Windows Mobile marketplace 'the place to
  be? for developers wishing to distribute and monetize their Windows
  Mobile applications. 

Okay, they said "place to be," not "place to go."
But that's just a grammatical thing: Developers will want to "be"
there, while users will want to "go" there.  Or so Microsoft hopes,
anyway.
