Nice little board but, increasingly, I find that such low pin count devices are becoming less and less useful for my projects especially with all the pin sharing current microcontrollers do. By the time you use a few of the on-board peripherals you end up with very few/no GPIOs. Teensy 3.2, the Pro Mini, this board all fall into this category. I love Teensy because of it's M4 processor but the board layout/pinout is a challenge.
Anyway I'd find this board much more attractive if it used a ATSAMD21J18 and was lengthened to accommodate the additional pins (8 per side). The 16 additional I/O's would make it much more flexible and useful for a larger number of projects. Is there a marketing reason backed up by actual data that says you have to stick to so close to the Pro Micro /Teensy form factor ?

Read the specs - 1.2A output for the four of them. You need a powered USB hub for a decent wifi dongle.
Ok, but you are confusing a distro with the board. The BBB is more compact,much more robust and substantially more powerful but, unfortunately, the extra USB ports on the PI are a MAJOR advantage for many uses. The BBB's single port is often a drawback for my projects where I want USB WIFI and a couple of USB<->RS-232 ports. Lately, I've resorted to not using dongles at all and have started using cheap/small client adapters like this - http://www.amazon.com/NETGEAR-WNCE2001-Universal-Internet-Adapter/dp/B007CO5DZ4/ref=sr_1_1?ie=UTF8&qid=1405732223&sr=8-1&keywords=netgear+2001 on some applications

I'm sure this board is useful to many however it defies me that no one - including Spark Fun - makes a shield using P channel MOSFETs in a high-side switch configuration. That would be SOOOOO useful for so many projects. I find myself having to always build a temporary breadboard whenever I need a high-side switch which seems like most of the time - especially for implementing dimmers for lighting that already exists in a device (like an automobile or other vehicle).
Can you guys please do a high-side version of this? That would be awesome!
No public wish lists :(
