im guessing either they're copying Apple, or it's supposed to be like 'my google'

I is there for independant

In a move that proves that Apple does not exclusively own the prefix “i”, Google has officially renamed its personalized homepage service ”iGoogle”. With the “i” prefix synonymous with Apple, on first hearing about iGoogle, I thought that perhaps Apple had bought Google, or more likely, that Google had bought Apple. But no, it was nothing as nearly as exciting as that (though if either of those things happen, remember you read it here first). If you’ve never played with Google’s personalized home page, or iGoogle as it’s now called, it allows you to create your own personal Google homepage by choosing “gadgets” to have instant access to information and other services that are of interest to you. More than 25,000 gadgets are available. Some examples include Quote of the Day, Date and Time, Gmail, News - Top Stories, Pac Man, Soduku Puzzles, and Horoscopes. The team behind personalized homepages wanted to call their service iGoogle from the beginning, but they were overruled by Google co-founders Sergey Brin and Larry Page, according to Marissa Mayer, Google’s vice president of search products and user experience. That explains why the URL for personalized home pages has always been www.google.com/ig. With Apple’s stranglehold on the “i” prefix finally broken by a major company like Google, will the floodgates now open? Let’s face it the letter i is pretty cool, and there’s no reason why it shouldn’t be shared around the computer industry so that more companies can benefit. http://tech.blorge.com/Structure:%20/2007/05/01/igoogle-breaks-apple-stranglehold-on-i/

iPod, iPhone, iMac, iAmOutOfControl! i think they are just following the (annoying) trend. kind of like a few years back when the cool thing was to add "e" to everything. email, eFile, etrade...
