Yep, this in obvious downside/difference compared to N800. However, as we have seen from the smartphone/symbian market, only a (relatively small?) subset of consumers really wants to install apps. What many consumers care about is easy, intuitive, and solid implementation of the pre-installed apps. Here Apple is giving a real challenge to Nokia et al, and I truly hope they will rise to the occasion. As Nokia Nseries chief just put it, this is not a huge threat to Nokia yet and more an exiting development that should make Nokia also better.
