Looking for low power consumption OS for Arduino IDE

Hi Dude,
I'm looking for low power consumption OS for Arduino IDE, because I want to monitor serial data for six months or more using laptop. As everyone know that Windows is kind of power eater so please make suggestions.


Get a netbook size computer that runs at slower speed, solid state hard drive, & lower power consumer to start with.

I'd suggest another arduino (or preferably but more difficultly a bare atmega328p) with an SD card.

The next level up would probably be a raspberry pi-like device.

You don't want to run the Arduino IDE to collect data. That's done with a much simpler program that reads data from the serial line and writes it down in a csv-formatted text file. As WizenedEE suggested, a "data collector" arduino with an sd card shield would probably be fit.
