And not to forget: bang for the buck!

Do I need to pay $2000 for this now or can I pay $200 for it in a year or two from now?

E.g. I just bought a new phone. It's two generations behind by now but actually has better features for what I care about than the generation after it. I.e. I wouldn't but its successor if that was the only phone available to buy. I would stick with my 6 year old phone instead. I didn't even bother checking the current generation because that's always too expensive for what you get.
