I wasn’t trying to start an Android vs iPad war, but since the ultra high res (2048 x 1536) screen of the new iPad seems to match the needs of professional photographers more than any other tablet on the market I thought you might have to see it for yourself.
Btw, the connection discussion is pretty old. Get a USB / sd card connection kit at eBay for less than $5 incl. shipping and you’re all done. Same goes for Hdmi cable etc.
Don’t forget the quality & quantity of apps, especially tablet dedicated apps.
