I think a lot of people would argue that sticking with their current system (banks, fiat currency, etc) is, in fact, much easier than that.
Seriously, the interface provided by Citibank is pretty freaking great. I work, I swipe my credit card places. As long as I do the former more than the latter, I don't need to touch anything else. Also every few months I accumulate enough points to buy something on Amazon for $50-$100 for free.
Bitcoin could be even better if I got paid in Bitcoin and could pay people in Bitcoin, but I can't.
Electrum is great and if you write down the words thats fine. If you try to memorize them without a backup there are a lot of events that can happen in your life that will lead to the total loss of your coins.
