I have a N900 but bought my wife a Nexus One. Her phone seems to have all the features the Nokia is missing (reasonable battery life, mms, snappy UI, turn by turn etc etc).

It had seemed the N900 was a better choice for me because I like to tinker with the device but I am starting to have some serious droid envy.

Watching her locate the nearest Starbucks faster than I could get the N900 maps application started was embarrasing. Then the Nexus gave voice directions to the coffee shop, something the N900 cannot do.

My kids thought it really funny that my "flagship" Nokia device lacked so much functionality.

The final problem .. the N900 refused to charge overnight even though the battery icon indicated it was charging. I had almost no battery the next day. Not amused.
