That was rather my point. Has Apple charged for ANY of the iPod Touch updates? If they have, I'm not aware of it.

You must have an amazing Palm Pre to not get the "No additional cards can be opened at this time" error message that pops up when I try to get the 7th or 8th card open. The Palm Pre is the best illustration yet for why blind, pre-emptive multitasking in a phone OS is a bad idea.

Exactly like they did for all the iPhone updates that have worked on all the original iPhones.

They only lean toward MAC/IP topologies in BPL. In lower-bandwidth scenarios (metering) they go a variety of ways, largely because extended distances mean signals from a given node won't be visible across the entire network, which forces a repeater mechanism of some kind. It gets complex fairly quickly, especially in commercial systems, where huge banks of fluorescent lights create some unpredictable behavior.

Making things worse are the customers who have heard about BPL and say, "Why can't you just replace all these devices with something that does broadband and greater throughput?"

Actually, the way they do this is using an address layer like most any other protocol. A bunch of different topologies exist, but generally speaking, each monitored node will be uniquely addressable with a value embedded in the data frames rather than just by frequency. Multiple frequencies are used to dynamically adjust to the presence of various types of noise.

People said the same thing when they launched the Zune. Go figure. - Tim
