I backed up my phone today so i thought i would share the videos I mentioned.
This is a before and after comparison (33mb): http://smebo.co.uk/video/dtuk_box_before_and_after.wmv
It's easier to time in premiere than on my phone, i said 13sec and 10sec but if you start when you hear the stupid sport mode drone kick in and stop at 100mph on the display i make it:
Before - 3sec - 16.7sec = 13.7sec
After - 27.7sec - 38.6sec = 10.9sec
2.8sec or 20% quicker
That looks pretty swift. I bet a few people will have their nose put out of joint.
