Where’s anyone saying it’s worthless? That’s not in the article nor in these comments.
The issue is how it’s being used. It’s not being used to detect cancer. It’s being used for “efficiency”, which means more patients being seen by fewer nurses. It’s furthering the goals of the business majors in hospital administration, not the nurses or doctors who are caring for the patient.
How so?
I use Firefox most of the time, but if I really need to stretch the battery life I’ll use Safari. It seems significantly faster and more power efficient than anything else I’ve used. If it had better plugin support, it’d be my daily driver. Can’t say I’ve ever had issues with it rendering a page.
