I have a couple of Spyders but never that impressed with them for what they do. I got into some go-round with Datacolor over them when the last one wanted to do some auto-update to the latest version than the CD I was loading and I allowed that. Then it would not work for a week until they issued me a new serial number since the one on the disk I had wasn't compatible with the new downloaded update. (Shade of Windows 8.0 to 8.1 too!).
So I bought a ColorMunki Photo. And now I see they added the ColorChecker Mini to the box and you can profile your camera now too, as well as a monitor, projector, and printer too. On sale for $409 from B&H too:

Their i1 DisplayPro will do tablets and some phones with an app that the above won't do since it takes the battery juice of the device to run it off the device's USB cable. The Munki takes more juice to run so it won't work for those handhelds. Trade off is it won't do printers or camera calibration.
