maybe luxurious is the wrong way to put it, but the iPad has always been marketed as a luxury-segment product. it is promoted as being something special, not just another everyday CE device.
the iPad is like a backyard swimming pool - you don't need one, but it's fun and all your friends will be impressed. the kindle is like a washing machine - you don't need one, but if you don't have one you're going to be going to the laundramat/reading paper books like a barbarian.
No, I think the iPad is like a veranda, and the Kindle is like a block of cheese. No, wait, the iPad is like a BMW, and the Kindle is 40,000 frequent flyer points. No, that not right, the iPad is like a Ming vase, while the Kindle is like a big screen tv. yeah, that the way.
You analogy is only slightly less awful than mine.
