The Arduino Uno Rev3 SMD is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip.
1. Additional features coming with the R3 version are:
2. ATmega16U2 instead of 8U2 as a USB-to-Serial converter.
1.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the   board and the second one is a not connected pin, that is reserved for future purposes.
3. stronger RESET circuit.

John Doe –
This is my second device from Apple.In the past i have used a bunch of laptops and usually switch them after a year and so.Mostly i bought products from HP and lenovo.The last one was Lenovo Ideapad Y510,which was kind of a good device but bad battery life for a traveler like me.
So, the main reason i bought the macbook pro was the good battery life and excellent performance it offered.
Apple MacBook Pro MF840HN/A is the latest version of this one http://amzn.to/1EvEWcb

have had this laptop for 10 days or so, and these are my thoughts –
I am a long time Windows User and what I love in a Laptop are two things – Resolution (w/ Screen Quality), Performance and Build Quality. Now, make no mistake – this is not by any means the highest resolution laptop you can get. (Dell XPS 13 sports a ~4K screen). But what people forget is one thing –
Windows. Scaling. Sucks.
