Not sure if i go Android can anyone help me

[miz@r]

Hi

I use to have a HTC diamond from sprint. Now there are very few WM htc phones out there. There are more Android options. It seems that i will go for it.

My bigest concerns are:

conectivity with outlook since all my contact, emails and stuff are in outlook. Of course I will want to email with the android. My primary account is POP can I use it in the device? as primary email?

Office documents, msn messenger, therering and ROM upgrades.

The other thing i love my Garmin Mobile XT in the old Diamond is there any garmin option for android?

Thanks

my adroid options are:

HTC hero, this one I can get with a really good price
HTC incredible
HTC evo shift 4
and not sure if i can get the HTC evo

Any comments on those phones?
