Hey guys is there any good Android tablets out here 'compareable' to IPAD/Playbook?

I know all three are running on different OS, it just that i was thinking of getting an IPAD - for tablet use (since i already own an Android phone), but after play it for quite sometimes with my friends Ipad i find it a little too big for a tablet.

Any tablet that comes with normal "book size", easily customizeable (popular so it has a lot of so call 'updates' both official and in xda? )

Just want to survey for the best tablets. Hope you guys don't mind to throw in a few reviews if you ever stumble upon one.

p/s : I've read playbook reviews in LYN, it seems that playbook are quite neat and fully featured. It just that..it would be nice if I already had a Blackberry.

Regards,
