It wouldn't surprise me if Dr J used the word "unstable" to describe WCDMA or DS specifications and/or standards but I don't recall that. I don't think he would have called WCDMA itself "unstable" since there are many possible flavors of WCDMA and Qualcomm is developing their own WCDMA also. I am surprised no one has commented on my intuitions that WCDMA has some practical hurdles to overcome in terms of battery consumption, handset size and cost before the technology can hope to be a commercial success. I think we can safely assume no one has released a pre-production WCDMA chipset, either for handsets or bases or whoever it was would be loudly tooting their own horn. This means the much touted WCDMA "trials" are not using handsets as we know them. I would think 1xrtt would have a power advantage over WCDMA which requires a wide spectrum to be decoded, regardless of the data rate being delivered? Also the filtering is more complex, thus requiring more power but I don't know how much more. Since 1xrtt can deliver speeds of at least twice a wired modem working at peak rates, I can't imagine a pressing need for faster data rates until applications that require even higher rates become available. At 100Kbps, the quality of the various web servers being visited will determine the apparent speed of the connection more than any speed gain allowed by a move to the 1.2Mbps speeds allowed by direct spread technologies. Capacity shouldn't be an issue either. If there is enough spectrum available to deploy WCDMA, then there will be plenty of bandwidth for a few years, even using 1xrtt which does not use the spectrum as efficiently as DS technologies that are being developed.
