Although we have yet to finish the 2015 season, our team considers the 2015 control a significant improvement from the cRIO system. NI, FIRST, Alpha/Beta testers, and WPI have all done an amazing job once again.

The new system is cheaper, lighter, smaller, and faster - what more do you want?
The roboRIO appears to be quite robust, but not as heavy as the cRIO and can survive abuse from FRC competitions.
The PDB is smaller and lighter, and has built in current monitoring that works very well after you update the firmware.

The VRM seems to work well, though it is possible to burn out one of the supplies when it's run at full current for a long period of time. The connectors are much better than the old ones.

The compile/build/deploy times for Java are much faster than in previous years. Also, the imaging the roboRIO and setting up all the control components took me quite a bit less time than the cRIO, which I have a lot more experience with.

Minor issues:
PDP log files - they're saved on our computers, we send them to people to help us solve problems, but teams have no way to extract/view data (except for the name of the event they're currently at) from the log files.

There's no accurate timing on Java anymore for TimerTasks. This makes PID control or other control loops behave strangely.

The d-link radio still takes forever to turn on. Start up time for wireless connection hasn't gotten any faster even though the roboRIO boots much faster than the cRIO.
