Having only joined the tablet bandwagon with the new Air, I'm rather new to this whole different-apps-on-the-iPad thing. I was kind of surprised that a lot of apps weren't universal. I hadn't bothered to look at the Apple Store app yet, but it's good Apple has finally made an iPad version for the next time I'm up at 3 AM ordering something. It would have been somewhat jarring to see it was a 2x iPhone app.
