I had one for a year with 140 tables on it. For the money and given its limitations, it was quite enjoyable. I have about a dozen pins (give or take at any given time), so I was not often drawn to the virtual pin, but I think it is a reasonable option for someone with very limited space and/or funds.

^ I don't disagree with this, although I still think I'd rather have one virtual pin than one traditional pin. I'd get bored with the latter a lot sooner than the former.
