Increasingly different numbers between AdWords and Analytics

Yeah, I know why there is a difference, but why is it now getting bigger

I was just wondering if anyone else has seen an increasing difference between the number of clicks that AdWords reports and the number of AdWords visitors Analytics reports?

I know why it happens (difference in how it is reported, JS not loading, yada yada yada) but across the board on many clients sites that difference has been getting bigger over the past few months.

Anyone else seeing this? Anyone have a suggestion as to why it is happening?

Yes, only half of my clicks turn into actual visits. So I'm losing half of my budget. This isn't cool.
