Apple Thoughts: iTunes Match, A Review

"Earlier today, Apple finally released iTunes Match, about one month later than the service was originally expected. Now that it is here, consider this our first look at Apple's highly-anticipated new product."

Here is a brief run through of how the service works, the main point being you have to update iTunes to 10.5.1 before you even get started. I don't have a huge amount of music, but for those that do, this might take some time to run before it is complete. I wonder how many will hit their data cap while using this service? Or is that even a concern?
