Use the 80 Bryan, I'm surgically attached to mine, it works the same as what you are used to.
The 90 doesn't bother me in the slightest. Video... Who cares? I bought it for photo's! 15MP... Who cares? Your glass doesn't resolve that much so you will get sharper pictures when you turn your 80 back to 6MP!
The most important button on your camera is the +/- next to the on off switch, use that in conjunction with your histograms and highlight warnings, make some great photo's, bring them back and show them off
