Many of my friends have PCs. Even my girlfriend has a PC and I did the last Tyros update with her computer. Still, I hate to carry my keyboard because of one damn update. I have to remove the music stand and speakers every time I want to carry it, because with the it doesn´t fit in my keyboard bag. The same thing happens if I go on a gig. The truth is that PSR9000 was very handy compared to Tyros even with the weight. Otherwise I am very satisfied with my keyboard. Someday I will write my review of it here.
I don´t think it is economics why Apple decided not to have floppy drives in their computer. Apple has a DVD-R-drive which is very important for me. As a video professional the DVD is the best format for me to share my stuff and more and more of my customers wants their video program that I made on a DVD. Not on a bad quality VHS.
