How many bikes is it right to own?

I personaly would'nt class a 29er as a separate bike type, it still falls under the other sections.

When I talk to people about 29ers, they seem to be thinking about getting a rigid niner as an addition to a collection which already includes a hardtail 26er, so they are probably different enough to count.

Oh, and apostrophe placement fail, as this is a grammar/spelling thread too.
