Good questions. I've always been fascinated by the Azores and that would be my first pick, but I don't speak Portuguese. Canada would be the best to purchase based upon resources and other things, but its way too close to an oil addicted bully...
I think the best bet would be New Zealand. Great climates, island, decent industry, English, lots of mountains to build super scientist bunkers in, connected but kinda secluded in the global scheme. Good place to be king / evil super scientist.
I would go and visit my relatives in the future. Less stress and pressure in this life knowing that no matter how bad I screw up its not bad enough to end this genetic line. Plus I could tease everyone about how wrong they are about where tech is going, and it would be nice to see how New Zealand is doing under my family's rule.
If I went back in time I know I would screw something up big time... plus its pretty much impossible, getting back to this time would be a pickle...
