Yep, I was about to order two new 64gb iP5's to replace our out of contract iP4's.
Then I thought about all the dock connector accessories we have: half a dozen ($100+) speaker docks scattered around the house, gps cradle in one car and full iPod integration in the other, withings blood pressure monitor, a ton of charging and sync cables, car chargers, travel chargers, battery packs, video out cables, etc, etc.
Anyway, the thought of giving up the convenience of all that lot made me buy two iphone 4s's instead. I'll be sitting this transition out for a couple of years. Hopefully prices will come down and the stampede to buy adapters and accessories will be over. I remember what it was like when the iPad camera adapter came out. Folks were grabbing them to sell on eBay for double the money. It was impossible to get them at retail for quite a while and that was for an item that wasn't really essential. I predict a bloodbath when the lightning adapters start to become available (unless apple have stockpiled them and are ready to flood the market?)
Just to be clear, I really like the idea of lightning. It seems like the way forward technically and I'm sure its full capabilities will grow and be revealed over time (unlike the old connector that's a fixed-pin dead-end). But the transition is going to be painful.
