Here’s a tip, sell your “old” one, to buy a new one.
That’s how I got my new Samsung Galaxy S Tab 10.1. I sold my Blackberry Playbook (do to a severe lack of apps) in order to afford a new tablet. If done right, you could switch devices every six months using this method of “buy, sell, buy” that I’ve seemed to have developed a knack for.
The trick to help keep retail value is to:
Keep the old device in the best condition possible
Keep the box and all manuals and such
Get cheap accessories, to help boost overall value of bundled product
Research prices on eBay and Amazon, and price yours in-line
These few steps can help you get that new device you’ve been dreaming of.
