Grief, there is only two of you and one copy will do two computers no problem.Pretty sure two copies costs twice as much. Replacing one license of Aperture for me requires between two and four licenses for LR, depending on how much faff I want to put up with, regardless of whether it's standalone or cloud.
This bleating about "oh, just get this stand-alone version" is completely missing the point. The payment model is not the issue. The issue is the number of copies I'm expected to buy to replace a single copy of Aperture.
Yet is may technically not be quite right according to the licence, but I think Adobe realise that's how it tends to get used in the home environment. If you are using two computers each than pony up for a second copy, it's well worth the money.You obviously can afford it if you have 4 computers to run it on.
If you are talking about a workplace, buy two copies and claim against tax, again no big deal.
