Teensy 3.1 back side pins

Although having a number of the pins broken out to SMD pads on the back side of the board keeps the physical dimensions small (and consistent with the "Teensy" moniker!), their use requires a number of workarounds, some more cumbersome than others.

In future iterations, I would vote for a larger physical size of the board by bringing the pins (even a subset of them) to the front side in some fashion.

For reference, the solutions mentioned in this thread especially referencing this adapter board are very helpful in the interim.
 
The impression I get is that very few projects would benefit from more pins. More would benefit from a smaller firm factor. I suspect more people like the idea of being able to "use everything" than actually do.

If anything, I'd suggest an option to buy a Teensy with a high density connector already soldered. The connector could match a popular display and a breakout/carrier board.
 
There is a store on tindie.com that provides a breakout shield for the bottom pads, and for about $60, they will provide a Teensy 3.1 with the pins soldered in: https://www.tindie.com/products/loglow/teensy-31-breakout/. If you are solder challenged where soldering pins to the pads is a problem, this might be an option.

Another breakout board (sold without a Teensy pre-soldered) gives you an Arduino shield layout for the pins common with Arduino: https://www.tindie.com/products/freto/teensy-3-breakout-board-and-shield/.

Here is Jimmy Hugh's tutorial on how to solder pins to the Teensy 3.1: https://forum.pjrc.com/threads/26071-Using-all-Teensy3-x-pins-with-a-socket. If you just solder connector provided with the above two boards, be careful in removing the Teensy, as people have ripped the pads off. Jimmy Hugh's method seems sturdier (I haven't used it yet).

Onehorse has a tindie shop where he has a bunch of specialized shields that attach to certain underneath pins: https://www.tindie.com/stores/onehorse/.

Probably; though I have a specific application that prompted my suggestion about the availability of the pins on the top surface.

I'd support that.
