Playbook is a 7 inch tablet from Blackberry.. As blackberry sounds professional and superior build.. the tablet too stands up in terms of quality and premium professional features.. on the down side its a bit bulky and thick.. wifi only adds to the problems..
the top notch features are
1) HDMI slot for display, but even Ipad has this. The professional feature is missing. the presentation can be seen on tv but the user can see notes in playbook.
2) Bluetooth transfer even when the tablet is in sleep mode. so u need not pull it out and display ur gadgets before others while transferring files. Other cool feature is that bluetooth can let u connect keyboard to playbook.
3) Sync and backup over the wifi.
5Mp back camera and 3Mp front cam adds to professional quality. The build and rubber finish in the back also makes it unique.
Down side is that its for class and not mass people.. class means business class..
