For people that have had the iPad mini and have been using it for a bit - Do you see any checker-boxing when loading and scrolling web pages? It was annoying as hell on my iPhone 4 which just slowed to a crawl as time went by. My iPhone 5 is significantly faster and snappier than the 4. That is why I am concerned about going back to the slower chip and half the RAM on the iPad mini. Also on some hands-on videos I saw, certain apps and games seemed to take a long time to load on the mini. How has your experience been? Does the device feel snappy overall? If you had to compare its speed, what would you compare it to - iPad 2, iPad 3 or the iPad 4?
