Better if you need the extra two bits of resolution, but not better if 10 bits is good enough and you need more channels.
Not the same as an SD card: it's smaller, and not removable. That means you can't swap out the card to log more data, copy the files to another computer, or prevent wearing out frequently updated files.
Increased raw power is enticing: but not every application needs maximum processing power, and with the increased power comes some trade-offs that might eliminate it from some some applications.
Thats what I meant with the microSd. But theres the usb host for flash drives.
New Arduino Tian come with two standard antenna connector, one for 2.4 GHz and an other for 5 GHz.
extended wifi range could be easily by use antenna. 24 dBi antenna will make wifi range from 100m to 1600m.

Friis Transmission Formula with Propagation Law
R = Maximum range for communication link
N = Propagation Law (N=2 for line-of-sight, N=4 for urban environments)
PT= Transmit power
GT= Total antenna gain
λ = Wavelength
PR= Receiver sensitivity
FM= Fading margin
if in urban environments;-
Every 12 dBm receiver sensitivity gain will be double the distance.
Every 12 dBi antenna gain will be double the distance.
Every 12 dBm Transmitter power gain will be double the distance.
in line of sight environments;-
Every 6 dBm receiver sensitivity gain will be double the distance.
Every 6 dBi antenna gain will be double the distance
Every 6 dBm Transmitter power gain will be double the distance.

Wow, a beautiful board. I wonder if they will improve the bridge library. And I didnt see a microsd socket.

Arduino.org provides a new library called "Arduino Ciao" that runs on the Yun. I knew it at last LinuxCon in Dublin few days ago. I tried ciao and it seems to be faster and simplier than the standard bridge. Ciao is also plugin based, but at the moment it supports few protocols though.
mart256:
Is the Ciao implemented in linux, as bridge? Now I cant check the ciao documentation.
Yes of course, it's mandatory to allow interaction with high-level communication protocols easily. The library on the sketch side is really lightweight to reserve more memory to the sketch implementation, it's quite easy to use too. It take me less than an hour to master it. Most of the work is done on the Linux side in a transparent way. The only part a bit tricky is to configure "ciao connectors", because you need to edit a file in the Linux part, but only the first time or when you need to change connection parameters.
Analog Input Channels:12, 10 bit ADC channels
Analog Output Pins:0
Tian:
Analog Input Pins:6, 12-bit ADC channels
Analog Output Pins:1, 10-bit DAC
Tian is far better than Yun if you need analog I/O.
-->I wonder where this information is comming from..... There are some articles about it like this one or this one. But at arduino.org they write:
Analog Inputs: A0 - A5, A6 - A11 (on digital pins 4, 6, 8, 9, 10, and 12). The Tian has 12 analog inputs, labeled A0 through A11, all of which can also be used as digital i/o. Pins A0-A5 appear in the same locations as on the Uno; inputs A6-A11 are on digital i/o pins 4, 6, 8, 9, 10, and 12 respectively. Each analog input provide 10 bits of resolution (i.e. 1024 different values).
