Okay, as I bring this thread to a close here are my thoughts as a new TIPI user never having messed with one before.
1) It was easier to setup than I thought it would be.
If you can read directions (assuming they are correct), you'll have no problems setting one of these up.
Once setup, you may never have to deal with any RPi commands again.
2) Once it's setup, is super easy to use, although there are a few new things in the starter documents I'd like to see a more in-depth
3) As I get closer to "geezerhood", I found it easier on the old eyes to look at the hookup photos online, making it easier to see the details.
In closing... Would I recommend one of these to anyone? In short, HELL YES! There is an old saying, "Good things come to those who wait". Well, the waiting is over and as the former Texas Instruments spokesman used to say, "This is the one!"
