Ну с учётом того что пока для esp всё корявое, и документацию на чип публиковать не собираются можно и переплатить. (вопрос с ценой пока пропускаем)
Тут стоит учесть что есть разные задачи, мне не нужно работать год от одной батарейки, нужен просто нормальный wifi
А хороший контроллер впридачу совсем не помешает.
подвох есть, с эдисоном тоже не всё так гладко
Cons:
1. Edison asks for an power supply in range of 3.1-4.5V – the closest we use is a 3.3V, 5V is going to kill Edison
2. All I/Os are rated 1.8V, well that is good in general, but Makers just got used to 3.3V, level shifter … puuuh
3. To get console access you do need an USB/FTDI connection but the tiny 70 pin connector is not at all Maker friendly
4. To get access to the I/O pins – again these pins are on the tiny 70 pin connector
5. Dokumentation is … (needs some improvement!!!!), but we do like to hack into things to understand them

6. Features not completed by time of shipment (e.g. BLE – old BlueZ, no gatttool, …) – no release notes or roadmap …
7. 200mA min. and up to 600mA spikes is much but you do get a lot power! specially not for wearables

8. no analog inputs (compared to Arduinos), needs always and ADC e.g. connected via SPI extension
9. my not Wheezy (Umbunto) people are used to? … new tools, cross-comilaton, lot of hassle…
10. multiplex I/Os, analog via SPI … IO pin translation matrix … where is my A0 or D5 in Edison? … could be easy
11. bash shell is missing ;-(
12. default partitions are not well balanced – quickly reaching “disk full” …
к тому же все io находятся на мелком 70 пиновом коннекторе,
самое малое что нашёл

Note: The mini-breakout board (m-bb) does not have analog pins like the Arduino Edison board (AEb). If you wish to use analog pins on the m-bb, you’ll have to design your own circuit. (The add-on ADC/Arduino Sparkfun boards won’t fit with the m-bb). I wish this was specifically noted in the description.
