CryptoTab - Why desktop mining might be worth it (long-term)

I set up a CryptoTab page on my old laptop, and have been using it and sharing the link for a few weeks now. I've only accumulated roughly 0.0001 Bitcoin thus far, and I realize the objection to doing this is that "it costs more in electricity" than I will ever get in BTC. But I find myself thinking, what could this Bitcoin be worth in 5 or 10 years, what happens if this ends up being worth hundreds or thousands of dollars? Just a fun thought I had while watching the faucet meter continue to run up. If you'd like to join my CryptoTab network let me know. :P
