Hammers
Are you so sure about hammers being 'done'? Claw, ball-peen, dead-blow, lump, sledge, toffee... Wood, steel, rubber, plastic... How about the handles - again, wood, steel, or maybe plastic (GRP, ABS...) Not to mention power hammers...
I realise that probably wasn't your intention with the analogy and I'm being somewhat pedantic, but hammers, like software, do actually get tweaked and adjusted when what exists doesn't work properly for the current situation.
Now if you were renting a hammer (hammer as a service?) or a shower, you may very well find that the provider does decide at some point that what they're willing to offer does change so you end up in a forced upgrade situation, much like your hosting provider.
