All Windows Phones are updatable by Microsoft, and all Windows Phones *will* be updated by Microsoft. The question isn’t “if.” It’s “when” and “how frequently.” But they are going to do it.

Is there a high likely hood that first gen handsets will get stuck on 7.0 release and not be able to be updated to 8.0, 7.5.3, or what ever like with the current android handsets? my understanding is microsoft is trying not to have this happen but it seems imporntant with the release of these handsets only a few months a way.

For email, each account will have its own access point via a live tile on the Start screen and an entry in what I call the “All Programs” screen.

For contacts, all contacts from all accounts will be merged into a single list.

For calendars, all calendars will be merged into a single view in the Calendar application, but you can toggle the display of individual calendar sources (Exchange 1, Exchange 2, etc.) but not individual calendars within those calendar sources.

Why is this different for each item? We can only guess, but I’d chalk it up to maturity. I do expect a unified inbox option later, as well as the ability to mark/differentiate contacts and access individual calendars. It doesn’t matter what I expect though, since none of that is there now.

It seems that, rather then lumping accounts together by connection medium (Google, Windows Live, Outlook), the interface should instead treat each account as its own context. 3 different Exchange-based accounts in 3 different organizations cannot possibly be using a unified login account so why treat them as a single lump entity?

I am much less concerned about secondary Calendars. If that shows up in a later release great, but primary calendars in each account need to be fully functional.
