It's also much,
MUCH cheaper to trade in a tablet for a newer model...
I hope Android and Xoom do reasonably well. Giving Apple some competition in the tablet space is a
good thing. A competitive market benefits the consumer by pushing the manufacturers to improve their products and price-points.
I also really don't give a dang which platform works or "wins". I use what best serves my needs and will move to another platform if/when the perceived benefits outweigh the "switching cost". I used Palm products for years beginning with the Palm Pilot, Compaq/HP iPaqs when they were better, back to Palm on a couple models of Treo, then to Blackberry, and then to iphone.
Arguing about which device is going to trounce the other is just as stupid as little kids on the playground fighting over whether Superman or Batman would win in a fight. Who cares?
