The Death of Telephones
A few weeks ago I got my Cingular 8125 cell phone (aka HTC Wizard). It's a PocketPC phone (running version 5.0 of the windows mobile operating system). It is an amazing little piece of technogadgetry.
It runs a 195Mhz Texas Instruments OMAP processor, which is a little embedded CPU that has both an onboard DSP and a generic ARM core on the same die. It's kind of slow by today's standards (the phone was released over a year ago in Asia) -- most of the newer phones have 400mhz Intel X-scale processors. It's still pretty capable, though, and can reliably be overclocked to 240mhz. Also, given how quickly this thing eats its own battery, I'm glad the CPU isn't any faster...
But on to the subject of this posting, the death of telephones. What's most interesting about my phone are its networking capabilities. For example, the phone has 802.11b built-in, and can connect to Cingular's EDGE networking (again, newer phones do 802.11g and either 3G or EVDO, all of which are much faster). Still, EDGE is just good enough to do Skype calling with...802.11b is more than plenty...at least, when I overclock my CPU.
"What's so interesting about that?" you ask? I'll tell you. My cell phone plan works like this: $40 for 450 rollover talk minutes per month. Another $40 for unlimited data usage. I use Skype. Skype is $15 a year for unlimited calling out. In theory I'll never have to use those 450 rollover minutes except for inbound calls. I predict that this will become even more interesting if someone develops an always-on low-power networked VoIP telephony device -- minutes will no longer matter, only megabytes. Unless, y'know, net neutrality fails.
