The 'Google' phone that TBag are offering will be the G1, which is a decent phone but with looks only a mother could love. But the Android software it runs on is the only OS that can match the iPhone for user experience. It's every bit as pretty to look at.
If she wants a good camera though, both the iPhone and the G1 will disappoint.
I would recommend waiting until the Apple WWDC is over, by which time there should hopefully be a new iPhone announced.
I would also think carefully about what she actually needs and wants a phone to do. There isn't a phone around that ticks every single possible box, so think about the priorities and you'll be able to find a good match... with a little help from AVForums if needed
