You might want to take a look at ChartCase.

They have recently added XM weather. I have been beta
testing the 3.0 version and my strong impression is that
these guys do care about quality. And the team has been in
the flying business for a long time. IIRC they originally
wrote the flight planner that Jeppesen now sells, then went
off on their own to offer Golden Eagle via the DUATS
relationship. Definitely not hobbyist stuff as another
poster alleged CV to be.

As far as the satellites and keeping them in view, certainly
any system without an external antenna will have that
problem. I think they all use the same receivers.
