Thank you to everyone that posted their opinion or thoughts on the subject. In addition to being really entertaining it actually did help me think through the options and their relative benefits.
I've reconsidered my position on corrective lenses and will look into getting these on my current or new mask. I know I'm not getting any younger, so I can assume my vision will probably get worse over time. I may was well get used to the idea of the lenses. I already wear bifocals, why should I be so adamant against mask lenses.
The Luna is a superior computer (in my opinion) but is too large, expensive, and the graphics don't appeal to me.
The Cobalt is a pleasure to look at and from what I understand a snap to maneuver through the menus. This is the one my heart wants, but not the one my wallet wants. At least, not right now. They have some bugs to work out.
The VT4 is a nice PDC, great size, AI, dual algorithms, multi-gas, but a little expensive and I'm sure Sweetie won't like it. I still want us to have the same PDC for now.
So, by default and popular acclamation (from Sweetie) the winner is the Oceanic Pro Plus 2.1. I like the features, it's not the first generation like the Cobalt, the graphics are smooth (but not color) and very large, and it's AI. For a little bit more than the price of one of the computers listed above, I can get two PP2.1 computers.
Long term, we'll dive with the PP2.1 for a while. If/when I decide to go more technical or deeper (multi-gas) I can use my corrective lens mask to select the appropriate PDC at that time. Maybe by then the Uwatec will be a little smaller and in color. I know they have the beta of the trimix out there already, it could be a rock solid, trimix, OLED piece of sweet candy by the time I'm ready to buy again.
Thanks, Y'all.
