The playbook can currently be bought for anywhere between 99$ to 199$, which is cheap for a tablet.
The Playbook is said to be BB10 Compatible.
The new Playbook with cellular connectivity is around 400-500$.
If RIM is to release a new Playbook along with the BB10 phones, the price will easy be 300+ for the base model.
If BB10 goes well, the Current BB Playbook resale value will increase dramatically after it is discontinued. We saw the same thing with the HP touch pads, which initially started selling as much as double the fire sale price. (that didnt last to long but still a good point). The difference here is there will continue to be support for the Playbook even after this sale.
So in theory if you were to buy a 99$ playbook, a new one is released at price points 300+ and the current one discontinued, you will be able to resell it for 200$ or more.
This is just a crazy theory I thought off while I was bored. Please dont take it seriously, just looking for what you guys think
