1. Could I use Next to make digital backup of old cassette tape on the optical
disk? If so, how good the sound will be? (relative to the original tape, of
course)

2. I've tried to use the Nextstation displayed at MIT computer store
and was surprised to find that the I/O is so slow compared to PC or
Mac. 
	(1) When resizing the window, the border lines simply couldn't
		follow the movement of the mouse, or the symbol of the
		mouse on the screen. The lines delayed so much and jumped
		in so big steps (instead of moving smoothly) that I
		just couldn't stand it at all. Why is it so slow????!!!!

	(2) When loading and executing a binary file (application),
		there came a small revolving circle on the screen
		showing the computer was working and I had to wait.
		The problem is: I seemed to have to wait FOREVER for
		the program to start. The startup step of almost every
		program took so much time that I just couldn't imagine
		that was a Nextstation with a hard disk instead of an
		Apple II with a floppy. Again, why is it so
		SLOW????!!!!
   

I had put very high expectation on the Next computer (just think
about: unix system, real multitasking, audio processing  ....) until I
operated it myself at MIT. I would be very glad and appreciated if
any kind person tell me WHY IT IS SO SLOW.

Thank you and merry X'mas.
