Pushing buttons against a vertical surface or one leaned backwards when it's a keyboard's distance out of your way is very awkward.

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?
