Apple love to preach "the UI gets out of the way of your content" with each new redesign, but how true is that in practice? Let's compare the total height of the Safari UI with a toolbar, favourites bar and tab bar visible, across the three latest Mac OS design languages – Yosemite, Big Sur and now Tahoe. I've added a red line for emphasis.
It sure looks to me like the UI is eating more into my content with each redesign.
Pushing buttons against a vertical surface or one leaned backwards when it's a keyboard's distance out of your way is very awkward.
And at this point the technology is so cheap there's no reason not to include it.
It's about $100 dollars plus support e.g. for dust accumulation especially for the cheap devices.
Well unless your company's entire profit structure is based on charging exorbitant amounts for minor upgrades and making the lowest cost option almost always have some sort of glaring deficiency to try to push users to pay hundreds more than they need to for the "optional" upgrades that should have just been included and cost pennies on the dollar for the company.
That sounds like all the more incentive to provide a touch screen. What's your conspiracy theory for them not providing it, if not just that it sucks?
