I couldn't agree more!

Correction by Cell (CbC) has proven to be very reliable. However, with CbC and yesterdays technology, we are pushing the envelope on long RTK baselines which greatly affects convergence times. Also, as you indicate below, networked solutions haven't proven to be the most reliable so there's still a lot of kinks to work out with that technology. 

On the other hand, there is currently technology being used in the field today that will provide sub-inch accuracy out to a range of 30 miles, which 900/450 mhz can't touch. There's also technology in development that will provide sub-inch accuracy out to the 50-60 mile range and it won't be long before we'll be talking sub-inch at 100 miles. Couple that with the fact that wireless data tranfer will be done almost exclusively with cell, this portends a very short life for 900/450 mhz systems.

There's no doubt that CbC has some downfalls, but as far as Ag Leader's problems, I'm confident that they'll get it worked out before the Spring planting season.
