The new dual-core version is like day versus night Compared with the old single core sticks. And the built-in bluetooth leaves Both USB ports free so I can use a USB mouse and connect for example a webcam for Skype (also works well with dual-core) and a harbor-have for over a USB stick.
The only negative points on my model is que la microSD card is a little deeply set and it is hard to get the card in and out.
