We've asked it before, but as the seasons change, so do preferences in mobile operating systems.  What's your favorite mobile OS right now?  Personally, I tend to switch back and forth between Android and iOS depending on my needs that week, along with an occasional jaunt into Windows Phone as the mood strikes me.  I've never been keen on using Symbian, Maemo, or Bada, for my personal use, though I can certainly appreciate what they bring to the mobile OS roundtable.  And who can forget webOS?

Summer's here and there are some hot Android smartphones on the market, along with a fresh build of iOS that'll be rolling out in full later in the year.  So I pose the question yet again.  Which mobile OS is your favorite?  Cast your vote and let me know in the comments!
