Jos,

In my opinion you are comparing 'Appels met Peren' !!
I have no idea where you think the latest technology has arrived in the upper class keyboards.
Modern keyboards do have harddrives, several Mb's of memory, flash-able OS'ses, pretty good displays etc.

You are messing up the 'core businesses' of two totally different machines :

a. Arranger keyboards = creating top quality sounds/styles.

b. Media Stations = handling all kinds of media-tasks. (creating music is only one of the features)

For a musician it is the highest priority to have good soundquality. A hi-res screen has a very low priority for him/her.

I own the B4 (Native Instruments) and like it very much, but an arranger keyboard in a PC ?

"20 years behind " ? ....... you'd better visit a music-shop/guitar centre very soon.... and you'll have to correct your statement I guess

Proost !
