Your answer is logical, Bachus:

Budgets are important. I wish my Government would stick to a budget and "live within it''s means" like I must do. The thing about budgets in Corporations (coming from a corporate background) is that they are meant to maximize profit and minimize waste.

At the prices Yamaha charges for it's "high-end" models, Genos, Tyros and the PSR-S series of machines, increased sales enhanced by features that would not break the budget would more than offset the cost of cheap USB ports... in my opinion. Not being a Yamaha "insider" I cannot prove or disprove my theory... but I suspect they could easily incorporate such a minor improvement in their future models. As Donny would say, "Just Saying!" LOL!
