I expect the win2 to be priced somewhat around current switch price, will it have the same horsepower? On the gpu side it is not but, unless you are really into Nintendo games, the win2 can be a good alternative for various reasons:
1. If you are already into pc gaming you probably have tons of indie games on steam from super cheap humble bundles;
2. Cheaper indie games and a lot of classics already available;
3. Huge storage and upgradeable too
4. It is also a Windows machine and so it is way more flexible;
5. If you are into emulation you can do a lot with it.
It's not for anyone but there are enough reasons to consider it.
