My MacBook Pro boots in less then 15 seconds since I installed a solid state disk. That's 14,5 secsonds slower than the calculator, but from then on I have all the power of four processor cores working for me :-) BTW: I always turn it off completely when not in use, even if in sleep mode it consumes only a fraction of a Watt of electricity.

One day per week I teach ground school to student airline pilots. I do lot of it in the old style and actually draw a lot of graphs on the black board. So the answer is yes (I did it recently) and yes (I enjoy doing it) :-)

That is true of course. Working with the data yourself gives much more insight than looking at computed results. But I still don't see a reason for doing statistics with my bank account. I mostly spend money because I have to and there is nothing I can do about it. With obe exception being my collectibles (calculators mainly) and there again you have to take it when it comes up because there may not be another one coming... (I just got a box containing my last missing LED calcaulator from HP in the mail, an HP-29C. I have not dared to open the box yet...) Would I have passed on this auction I might not have got another chance for years to come - at least not within my financial limitations - therefore I had to take it regardless of my account statistics!

Not directly, but indirectly. Recently I bought a LiIon powerbank with an integrated solar cell for ridicuolsy little money on eBay. You keep it lying on a window sill during the day and every night you can recharge you phone(s) and tablets and complex calculators from it. So I can now say that all my rechargeable gizmos are solar powered.
