After a few false starts, today I received my Galaxy Nexus purchased from Mobicity and so far this phone is definitely living up to my expectations. The Nexus is not as wide as I expected, it fits in the hand quite easily and is pretty manageable for one-handed operation. It is light, much lighter than I thought it would be, and is also remarkably thin.
Ice Cream Sandwich is polished, quick, and feels like a major upgrade from Gingerbread. People who have used a Honeycomb tablet will probably adjust to it quickly, but coming from a phone running CM7 I know it will take me a little while to get used to it. I will definitely miss my 32gb microSD card which has served me well for the past year or so, but adjusting to the 16gb onboard storage is worth the sacrifice to use this phone.
One of the Ausdroid team will have a full review of the Galaxy Nexus up within the next week, in the meantime feel free to ask questions in the comments.
