Which iPad 2 should I get?

Marco Arment of Instapaper:

If you’re happy with your iPad, there’s not a huge reason to upgrade. Casual gadget customers who already own iPads are probably better off waiting for the next version.

After reading this, I’m now questioning myself. Maybe I should hold off until the next version. Marco, however, is not:

Good luck. I’ll see you on line at the Apple Store, where I think I’ll be getting a 32 GB Verizon 3G model, in black, with a red, navy, or black leather Smart Cover.
