I've been contemplating getting an Motorola Xoom when the Android version of Logos is available. But after seeing the HP Touchpad in action I really think they have the best tablet OS in their WebOS:

Too bad Logos won't be available for it. I suggest it should be. ( I'm not keeping my hopes up though.) I do really wish HP/Palm would succeed in breaking into the market.
