You can get a better deal on some consoles at the moment, but I wouldn't count on that to last. The Switch 2 has a price increase scheduled. The Xbox line has a price increase scheduled. PlayStation did one earlier this year. Rather than being a permanent situation this feels like everything going up, just irregularly rather than smoothly, so sometimes one thing feels like a better deal, sometimes another, but it's not obvious that any of them are much better on a longer time frame. If you're looking out at the console versus Steam Machine and thinking the consoles look better for your use case, you don't already have one, and you're interested in one of them, I suggest moving sooner rather than later.
The Steam Machine is what got noticed, and earthed a lot of anger about prices, but it's not particularly out of line or especially expensive. The whole market is screwed up.
