Apple recently announced details of its world-wide developers conference and observers noticed that training sessions and labs are focused around iPhone OS, Open ES, HTML5 and other similar technologies, which means that the WWDC will be heavy on iPhone and iPad, but light on Macintosh.

When it comes to smartphones, Apple (NSDQ:AAPL)'s iPhone may be top of mind, but mobile devices with Google Android guts pose the biggest threat to Jobs and Co.

According to a new market research study from Google (NSDQ:GOOG)-owned AdMob, the iPhone held about a 50 percent share of the global operating system (OS) market for smartphone devices browsing the internet in February 2010. While that statistic may not be surprising, AdMob found that Google Android is creeping up from behind, capturing about 24 percent of the market share. Nokia-owned Symbian placed third with 18 percent of the market. Meanwhile, BlackBerry-maker Research In Motion (RIM) and Microsoft Windows Mobile are left in the dust with a paltry 4 percent and 2 percent of market share, respectively, despite its solid smartphone sales.
