The new iPad

New iPad has great high resolution display. Some applications is already use it, but some still not updated and render in low resolution. New iPad has 1GB RAM and A5X processor. iPad 2 has A5 and 512MB RAM. CPU speed actually not changed. Only graphics is faster. Device heating up a little and weight noticeable more (+60 g). More time to charge needed.
