iGoogle – Only $25 dollars.
"iGoogle has 4 main features: Google Search, Google Mail, Desktop Search and News Search. All of which can be configured using the Settings feature and optimized to their full ability using the Support feature."

so? doesn't matter. they don't have the rights for that name anyways...

iPhone!= Phone
iPod!= Pod
iGoogle!= Google

Well, at least until the lawyers come in to play. And realistically, Google has a stronger case against anyone who was using "iGoogle" than Apple would against anyone using "Pod" in "PodCast", what with Google being a specific company name, while Pod is a generic word (dictionary.reference.com/brows ...).

I expect that it will simply be market share rather than legal action that pushes the other iGoogle products to change names.

iGoogle is also a Firefox extension published.... two weeks ago

Your two other examples are actual dictionary nouns (yes, Google is, but only in the sense of Google Inc). Google is a trademark, neither Phone or Pod are.

Anyone has the right to use Pod or Phone as they please, but Google is a trademark. If you make a product and call it an iMicrosoft or iDell you're going to get into "legal difficulties". Because using a registered trademark as part of your name without permission from the trademark owner is illegal.
