Would you buy/use a computer that ran 3x slower than modern machines if it were more secure (less vulnerable to side-channel attacks)?
Interestingly, the numbers are very different on here than they are on birdsite. Many more people here seem to be willing to take a speed hit for security here than there. Not surprising, I suppose: selection bias.
FWIW, I wouldn’t make the tradeoff (except maybe on a second computer) because I’m confident in my ability to avoid those kinds of attacks.

@suetanvil Really?
Do you never run javascript in your browser?
@cwebber
Rarely. I use NoScript and only enable it for sites I trust.
(Yes, I realize that’s not bulletproof because how much can I *really* trust a site but I expect actual wide-ranging in-the-wild side channel attacks to get on the public radar before they can reach me.)
(And that assumes such attacks are actually feasible and profitable.)
