There are no shockers in market tracker comScore's latest data on smartphone platforms.

Apple's (Nasdaq: AAPL) iOS and Google's (Nasdaq: GOOG) Android continue to gain in popularity, posting healthy market share spurts between February and May of this year.

Obviously, there can't be winners without losers, and Apple's and Google's success is coming at the expense of Research In Motion (Nasdaq: RIMM), Microsoft (Nasdaq: MSFT), and Hewlett-Packard's (NYSE: HPQ) Palm.

Let's take a closer look at comScore's findings, which pit the three months ending in May against the three previous months:

It's not a surprise to see Android growing faster than Apple. Several carriers and handset manufacturers are routinely putting out Android handsets. Apple is down to annual refreshes, and it's now been more than a year since the last iPhone update.

RIM and Palm -- the two companies that pioneered this space before Apple crashed the party -- continue to slide. Mr. Softy's decline isn't all that problematic now that we know that Nokia (NYSE: NOK) will be championing Microsoft's Windows Phone 7 as its smartphone platform of choice.

It will be interesting to see how the market shakes out from here. It's not just Microsoft with catalysts for hope. HP began shipping its TouchPad this month, and the webOS-powered tablet may rekindle interest in the smartphone operating system.

The widening gap between Apple and Google will also bear watching.

The iPhone was never going to be the smartphone for the masses with its high price points and reliance on the country's two most expensive wireless carriers for connectivity. However, the last thing Apple wants to be is a fading silver medalist in a niche it redefined.

Stay close. This race is getting interesting on many different levels.
