Sales of the popular and highly successful Raspberry Pi have hit the two million units last week. The creators of the $35 credit-card sized computer initially planned to sell a 1000 units.
It took a year to sell the first million and 8 months to sell the second. I bought two units myself last year. Raspberry Pi have been introduced to schools to teach kids how to program.
There are many uses for Raspberry Pi. The Linux-based units are used in variety of ways from running websites, mail servers, print servers, media servers, DNS servers, as well as automation.
Following the success of the Pi, there are other projects worth checking into in 2014.
