What is your Android Mt. Rushmore?

Whether it be smartphones or tablets, what 4 devices do you think best represent Android thus far.

HTC Dream (T-Mobile G1) - The phone that started it all...

Motorola Droid - The phone that sparked massive consumer interest in the platform

Samsung Galaxy Nexus - Pure ICS, the true Google Experience

Asus Transformer Prime - This is probably the choice that many of us won't agree with. I think its such a compelling device since the optional keyboard transforms the tablet into a relatively capable laptop with a ton of battery life and several useful ports. Its the first great convergence between tablet and laptop.
