esr also keeps a close eye on the developments in the mobile phone market. His latest blog post on this is at http://esr.ibiblio.org/?p=3493 , a short quote:

"Nokia’s strategy, insofar as it’s actually had one since the tie-up with Microsoft, has been to hang in there on volume sales of dumbphones until it could deliver world-beating WP7 handsets. The major risk here, other than the wild unlikelihood of WP7 ever becoming anything consumers actually want, was that the Chinese electronics industry would undercut them on price-performance. I predicted this would happen, it is happening, and Nokia’s disastrous July earnings call is the result."
