I own:

an Orbea Onix Dama (my normal bike for rides)
a Novara hybrid (for commuting, errands that involve it being locked up somewhere outside a building)
Some sort of Cannondale Mountain Bike (for camping trips or whenever my boyfriend can drag me on mountain bike rides locally - not often )

I will average 10 miles a week on the Novara commuting to work, I hope to get in another 90 per week on the Orbea to average 100 miles per week this summer. But ski season isn't over yet so I won't get started on that probably until mid April.
