Android phones, apps and tablets

So as a complete novice to all this please bear with me - The HTC HD2 is WiMo right? Why is that? So does that mean the Hero is pretty much the best Android phone out there? Apart from The Motorola Droid/Milestone are any others imminent?

The Samsung Galaxy/i7500 is the best.
It's endorsed by hippy enterprises so it has to be.
But you either need to use it stock or be a bit of a hacker with it since Samsung support is useless.
