It's cool to see this as a general rule. Electricity rates don't change very often, while Gas rates fluctuate quarterly, or sometimes even more frequently, making it difficult to compare cost. I'm in Colorado, and the cost of Natural Gas doesn't *quite* offset the Electricity cost for raw therms output to heat the house, but they're within $30/month of each other as of the last month's billing. They might actually be break even after Xcel kicks in it's quarterly increase for the winter months.
It's not enough value at this point to just rip out something functional just because, but when it comes time to replace the existing unit and I have to foot the bill anyway, a heat pump unit with gas backup seams more and more likely. The writing seems to be on the wall that electricity is the future for residential, and a lot of commercial stuff, regardless of how it's generated. I don't see power generation from NG going away any time soon though.
