the Raspberry Pi 2 is powerful, but you still get what you pay for.
The Raspberry Pi 2 packs more memory and a faster processor than its predecessor, which is enough to turn it into a more functional PC, but don’t expect any miracles: It’s still a $35 product.
The Raspberry Pi 2 was launched on Monday at an event in London, and is a big step forward. That’s because it has twice the amount of memory—1GB of RAM—as the Pi 1, and is powered by a quad-core ARM Cortex A7 processor running at 900MHz, which is much more powerful that then Pi 1’s 700MHz single core ARM processor.
These upgrades are enough to turn the Pi 2 into a usable PC
