Funny, I was in the Nunavut capitol (Iqualut) just a few weeks ago.
Ha, crazy. I wasn't even sure I'd spelled 'Nunavut' right 'til Firefox declined to complain. Well, at least you'll be one of the rare few familiar with the area when the Sino-Martian Alliance claims it as their power-base in the post-glacial Earthruin.
Ok, the combination of paying a low amount of taxes in 2015 (I'm already expecting reduced income) and the comfort of not having to track down the company that bought the company that bought my investment in 203X has convinced me. Jan 2015 I'll roll over into my ROTH.
Is your income/taxes really going to be that low? Usually people wouldn't convert a Traditional IRA to a Roth IRA until their income-from-labor reaches retirement levels, and only then in order to access the money without penalty before age 59.5. If that's you, then cool, but otherwise, you might just want to roll your 403(b) over to a Traditional IRA (which you can do immediately), and do the Roth conversion only when you need to.
