I bought a 64gb one a few months ago. I use an ipad for work and was getting feed up with the kids constantly pinching it to use as soon as I walked through the front door. For the money I think the Playbook is great, our one is now full of the kids DVDs and music (there is an app which connects to itunes). While there aren’t thousands of apps available I have found plenty of games to keep the kids happy.
When I bought it I took out the Currys’ 3 years what ever happens warranty, which does replace the tablet if it is accidentally damaged within 3 years. After owning it for a few weeks I had an issue with the charger port not working (I think the plug had been forced in upside down). Currys were excellent and replaced it on the spot when I took it in.
I have since bought the charging station for it which works well and charges faster than the supplied cable.
My seven year old son now ignores my ipad and his DS and only uses the Playbook. My four year old daughter seems more taken with the larger screen on the ipad. Construction quality of the Playbook seems good and is more solid than other budget tablets. Start up time is slow (like all BB devices), but from standby there is no delay.
