(for instance copying the entire contents of a window around when dragging, not to mention display postscript) The NeXT (slab) is not very expandible. How much CPU does the the interface take up while you aren't dragging windows around on the screen? The DSP in the NeXT is SLOW, and integer only. Even further, the NeXT It's a 10mip processor. The Amiga 500 is less than 1 mip. Also, Bzzzzt. The DSP does single precision floating point numbers. Please, reread your "Don't buy the NeXT it doesn't..." propaganda published by NCW. doesn't seem to share its DSP effectively. On the Amiga, the blitter chip is shared nicely. Its possible to 'OwnBlitter()' but it won't lock it completely. On the NeXT you'll usually see 'DSP Already in Use' I Keep seeing people harp about the fact that the NeXT has a DSP, but I have not seen it used much, unlike the Amiga in which a huge majority of software shares the custom chips effectively. Don't know what to tell you. You're right. Perhaps there are technical reasons for it. Sorry, thate was a mistake, it was supposed to read 'Takes months to get a NeXT' The NeXT is very backlogged, I priced them once, and everyone told me 'We have none in stock, and it may be a month or 2 before we get any.' vapor. Try again. I hope you get one. -Mike
