I'm glad I'm not swayed by every new product...never was much into getting the latest, other than the occasional keyboard...my speaker system is over 25 years old...my car is 12 years old...just sayin'.
I'll probably have my Tyros4 for a very long time...when you buy quality goods you don't need to buy as often, nor learn new OS and protocol...that way I can focus on improving my playing, not my button pressing skills.
Perhaps I'm old fashioned, but I believe in getting the most out of things before jumping to something new every few months.
But, to each his own...
