I really liked my Playbook thus far; much better than my iPad 1 and my Android eLocity A7 tablet which I gave to my parents. But there is one problem with my Playbook that I had observed at the Bestbuy sample units before I bought it. The problem is with the WIFI WPA 2 connection. Occasionally, it will simply drop the connection and sometimes I have to restart my Playbook to get a connection again. The same router works fine with all my Macs, a PC, iPhone, iPod touch, iPad and eLocity A7 without dropping the signal. Just the Playbook. Any thoughts. Again, it happened on sample units (more than 2 of them) at the Best Buy stores in Canada.
