Using a server installation as a daily driver

[TheNewStatesman]

Is there any reason not to use a server version of Windows as a daily driver, aside from cost?

Starting with 2012, probably not. The only real issue would be in regards to hardware or software capability. And it depends on what you mean by a daily driver. If you mean just using the internet, then no issue will be had. If you want to play games, that may be an issue with certain aspects if they (or the video/sound card) do not support the Server version. I think around 2012 to now, Windows Server is less transparent vs client, meaning most programs don't know any difference. 

But also in regards to using an old Server OS like 2008 R2, you are going to run into the same issues as equivalent client OS in regards to security certificates and TLS.

Regarding browsing - 7, Vista, 8, 8.1 and their server counterparts (incl. 2012) are all in the same shoes. All official browser support dropped for ages now. The last un-officially modded Chrome I was able to fire up is 125 from the last year.
