me too, but it seems that Qt Location is still the better choice over Marble.

only some tiles are wrong from Miika's case and we haven't found any
other problems apart from the "missing tiles" on deep zoom levels,
which tolerable and an issue for the Qt  team (e.g. "keep last zoom
level tiles if no further zoom level tiles are available). the wrong
tiles are broken on ESRI level and they should fix them ASAP if they
want reliable maps (i.e. that's a serious problem). our problem is
that we cannot report them to ESRI as they don't have a good
user/customer support.

like i've mentioned - someone from the US should get in contact with them.
we need this channel of communication if we find more bad tiles.

it's possible and i have this planned, but it seems that writing a
custom plugin for fetching tiles (e.g. from google) isn't exactly
easy.
on a quick look it seems like more work than our current Qt Location widget.

also, the QtGroundControl Google maps plugin that Tomaz suggested and
which already does that, apparently cannot be build on Windows with
MINGW as it requires MSVC.
