Stevizard said, "What we need isn't a full-fledged keyboard. We only need the arranger section but it must be built on a par with a computer. That is, it needs to have a removeable (therefore upgradable) motherboard, hard drive, scsi port, cdrom, slots for high-end memory, pci slots, USB, etc. We then simply midi it to our favorite keyboard. When better OS from any company arrive, we download and install them. Well, that may not sound very likely but its the direction we must go to avoid being taken hostage by the proprietary hardware and software of the keyboard manufacturers.

What do others think?"

Absolutely right on.
The new Roland EXR-5 has 10 watts per channel. Oooooooo.
The PSR2100 has 12 watts per channel. Wow!!
I can buy an 80 watt YSTMS50 powered speakers for $100.00 bucks and it's made by Yamaha!! Obviously, that is not Yamaha's cost. They could install a YSTMS50 in every keyboard as standard equipment. So should I purchase a new keyboard because it has a little more power, a few extra voices, a usb port? NO. I'm not going to play that game.
