Yup, you're right, my error -- Xoom already has Honeycomb.
I'd also agree that iPad and the iPad 2 is the more mature product, platform, ecosystem. iPad has 65,000 tablet applications available and Android has 100 tablet applications.
To the original poster:
If you want to bet on the underdog and want to suffer through some rough edges then by all means get an Android. If you want to bet on the more mature, more prolific product today, the leader in this race and the expected promise of continued support and maturity from the applications, then get the iPad2.
