Google Gears could be a major advancement for third-party, mobile developers.

RIM announced last week support for Google Gears on future devices, Windows Mobile devices already support it, and I’m sure Android devices are not far behind.

Why’s that such a big deal? Because the promise of writing once (for the web) and running everywhere is actually coming to fruition. And for developers, this is a big deal. One of the major cost factors in mobile software development is picking which platforms to write for. If we no longer have to make that decision and we can write for all platforms without having to re-write for all platforms, we will finally be freed to make a profit. What a novel idea!

On top of that, as I noted in my article regarding how other mobile companies can beat Apple, I spoke about how a company that enables web developers to write local applications easily for their device will have the inside track. Is someone at RIM listening? I hope so because Apple will be better for the competition.
