You mean street view on a ski slope? I suppose it is cool to have ski vacation virtually without actually doing it physically. After all, we can't ski every day in every season.
I have to admit, it is pretty cool. MS has PhotoSynth, it is much more high tech in regards to photo stitching, but, the end result is not as cool as having the professional using specially designed cameras to capture the environment.
As cool as WP Bing Map can calculate much cooler traffic aware directions (including street traffic), I have to admit Google is more dedicated to offer street view than Bing.
