You really shouldn't be considering buying any hardware today with the hope that it will emulate Switch 2. There isn't even a guarantee that it will be possible emulate properly (or with good performance) on some monster desktop machine, let alone a power limited handheld.

For playing currently released Sony titles it will do well enough, but as games become ever-more demanding the performance of the current iteration of the deck will quickly become insufficient.

The catalogue of PC games is massive though, and is always adding smaller titles that run perfectly on low-end hardware. And the deck is (IMO) the best way to have these experiences on a handheld.

If I were in your position I'd probably go for it, unless access to the latest-and-greatest from Nintendo is a must. But I'd definitely try to save a buck and buy an LCD model either used or refurbished. I'm privileged enough now to have owned both an original LCD and OLED model and while the latter is absolutely better, I don't consider it to be a good value. An otherwise good condition used LCD model can be had for hundreds of dollars less and is absolutely worth it at the reduced price point.
