Since I'm not a financial adviser, someone asked me take on which 4k projector to buy last Xmas.
I explained that the tech has improved so much lately, they've become somewhat affordable, I recommended a model and pointed ou that he would certainly get a better device next Xmas, for half the price. I thought he would follow suit given his budget was a bit below the retail price. That would just wait.
His response was he would rather go ahead and up the budget a few hundred dollars to get it right away. That projectors will surely get much better by next year, but that he, certainly, will not.
