Thanks. Thats the kind of thing I wanted to know.

Do you also have info about the PCMCIA performance of the Voyager? I
suspect that won't be on par with today's chipsets, too -- I've heard
10-15 KB/s for transmissions to and from ATAPI Memory Cards. iPaqs
should be a lot faster than that.

This fact should also further complicate things when we try to play back
128 kbps MP3s (or even greater bitrates) on a Newton -- that's 16 KB/s.

Ah, and some numbers about the throughput of the Newton's TCP/IP stack
would also be cool.
