Lafyar,
Basic rule of business is a thingy called Net Present Values (NPV's). The principle is simply, if I invest x amount now, what return does that x amount gives me over the next, say, 10 years (whatever 'life' the investment has) in TODAYS MONEY. You then work out (easy peasy on Excel) what return it gives over each year and then work back to today, the TOTAL amount it generates over the period. Essentially, working back from the year of 'fruition', you decrease the amount by inflation + whatever risk factor you decide to add (expressed as a % - about 6% is not a bad figure if investing in simple/boring stuff like savings) and arrive at the following:
X amount invested today MUCH lower than return = Invest X now!
X amount invested today MUCH higher than return = Don't invest!
X amount invested today similar to return = How big are you balls?!!
Dead simple and not to teach to suck eggs.....but not many people apply this to investments and there is no difference whatsoever (in principle) between buying a piece of machinery for your business or commuting/not commuting your pension.
By the way, not a geek (honest)...still serving as FJ mate....but do have a business on the side and the MBA (of which this was part of) helped!
Short answer.....Commute the money.......WHATEVER your circumstances!
