How fast will Ice Cream Sandwhich be Adopted?

This is a common question I keep seeing pop up across the web over the last couple of days.  So here is my small opinion on the matter.  Like every other Android release for any device already on the market, user's are forced to wait for the update to rollout to their devices.  Some manufacturers are better at this than others.  So obviously the adoption rate of Ice Cream Sandwhich; at least as far as existing devices out into the wild are concerned, will solely rely upon how fast smartphone and tablet manufacturers take to go through it and optimize it for their devices.  And no doubt add their own mix of bloatware to the update prior to sending it out to customer's hardware.  And as far as manufacturers are concerned they will obviously place the majority of their attention on their new products and filter the update to existing devices once that is done.

If manufacturers made it easier and more accessible to manually update our devices then you would see a much faster adoption rate for every future Android release.  But I definitely don't foresee that ever happening.  Just some food for thought.
