I don’t see how it would add bloat either… even if you end up running multiple display servers it only uses more resources when multiple users are logged in… proper easy to use multihead has always been something just out of reach on Linux also. There are potentially “security” issues with it, but only if you consider someone local controlling your computer to be an issue to begin with.

That’s the thing about doing things in an elegant way sometimes… it ends up being flexible enough that such features really don’t add bloat.

From experience what my family tends to do is buy each sibling a very slow computer… if they pooled all that money that could have bought something very good (think 32GB ram and 8 cores, instead of 4GB ram and 2 cores) and 99% of the time they use them only at home anyway. More things would be possible with the fast computer than on several slow ones. that’s the rationale anyway… if you believe it or not. The obvious downside is that it isn’t portable, but then you gain the upside of you would probably be able to remote into such a machine or host your personal files from it, and use a laptop that acesses it on the go (I do this all the time at work). There is definite value to a shared powerful computer arguably alot more bang for buck that say 4 powerful computers that go unused much of the time.

Oh on several occasions my siblings have had to upload videos for classes… thier slow computers took HOURS, to do a simple transcode… the hypothetical fast computer would have saved thier butts on several occasions.
