I have also heard that the modem is not upgradeable to 28.8.
I have also heard that the DSP is manufactured by Yamaha. It is completely
different from IBM's MWave.

again, net.rumor says that they did not have enough room in the 701 to stick
in the MWave, which is quite a bit larger than the Yamaha chip. perhaps as
the 701-series starts to use newer/smaller chipsets and/or lithium polymer
technology, there will be enough room for an MWave....
i use a 755CE, and i definitely love the MWave! if only there were 32bit
drivers for the MWave for, say, Windows NT.....
(the 16bit drivers do work fine in Win95, however)
