Consistency is good. But I find the update flow to be annoying. Touch 'updates' tab, doesn't show you the updates until you pull down (with no affordance), update are summarised but not listed in the big space for updates to be listed, "update all" then doesn't update all but instead lists the updates in that big space, tap "update" on each item listed, you get a popup asking if you want to update it (because the two previous choices of "update", after already going to the update tab, might have been a mistake?).

I appreciate it, but it's a weird flow. I'd expect touch "update" tab would run the "check for updates" without needing the pull down (maybe set a cache-time in settings); "update all" would do all the updates without any other taps (or with at most one [per app]).
