Palm Centro is reported to have surpassed the 2 million sold units barrier. How is that compared to Apple’s iPhone sales? Who is going to win an iPhone vs Palm competition?

Provided Palm will continue to update their OS and launch better Centros, they are likely to continue to sell lots of handsets too. Maybe not as many as Apple which appears to learn more and more things about the mobile business and even reinvent it in some cases.

AdMob statistics shows that more mobile ads are served to Palm devices than iPhones, whether we are talking worldwide or USA. Of course Palm has been selling phones for far longer than Apple has but the battle is about to begin.

Looking at both phones, the iPhone seems to have a little advantage at this time, with all the buzz going around it. Palm Centro is still going to be a worthy adversary and its fans will be waiting for lots of upgrades, including touchscreens, but not only.

So congrats to Palm for now, but we’re expecting more!
