I've got 5.
The Orbea hasn't been used since last summer. The Lemond hasn't been used since I bought the Orbea (and so may have to go to make space for a tourer). Used the Pompino over the winter months.* Full sus hasn't been used since last summer - neither has the the ss mtb.
* Up to Dec that is, snow & ice ruled out riding for a few weeks.
Then had the head drilled and chiseled to clear surfers ear.
Still using crutches three weeks after knee incident.
All in all, haven't been out on a bike since the begining of December. Having one and riding it seems the best option!
