You are right about the iPod however. I know a number of people who are on their third or fourth or even fifth iPod. Not because they really want to keep buying them, but they're locked in to iTunes with hundreds and in some cases thousands of dollars of purchased music that they can't access with any other device but an iPod.
If you want to help out your friends, do a quick google on how to get the tunes out of any iPod, it is pretty simple.
The version 2 is a long Apple tradition, typically it is 8 months, sometimes as quick as 5. There have already been some (unofficial) images of the interior of the iPad that show the space in the frame with the forward facing camera slot - empty for the time being. Apple will not be eating it's own lunch by making the device cell capable, any more than the phone was to the iPod. They are two different (with some overlap) markets, at two different price points. Again historically, they are pretty good with these types of things. Technically, the device is already capable, it is running the same cell module as the phone (including the gps module), and it has a mic, and is bluetooth capable. I would be very surprised if within a week or two of release there was not an (unofficial) cydia app that would make it possible.
As for people who loose interest because they would need a $30 usb cable/dock whatever, well not much I can say there except ya, ok.
As for the Flash, well it is what it is. Being an open source advocate, I cannot totally blame Apple for sticking to their guns as I do know that flash not done well is a hog. On the other hand, the amount of video's that use flash for a wrapper in web pages is so widespread that it is hard to fully understand their decision.
Anyways last post for a bit, don't want to hog the thread.
