specifically I tried to copy movies from my lap without any cable,as I do between my nokia and lap.The same with photos.I dont remember any more version of OS but whet I turned on for the first time it started upgrading to newer version though.I returned PB after 3 weeks back to Currys.
The fact that new BB10 is "on the way" does not mean nothing as hardware might no be able to handle it correctly.PB is 2 years old now so in terms of electronic this is a dinosaur
If you were copying the movies over to your Nokia phone the software you were using may have transcoded them for you automatically. More than likely this would make them smaller - that wouldn't happen with a PB. That would not be a fair scenario, because both devices are not being given the same amount of data.
Common sense would dictate that you'd copy large files over a wired connection. There are plenty of fair criticisms of the PB but that situation isn't one of them.
Your point about BB10 is actually realistic though. Considering the latest Blackberry devices have 2GB of RAM and a better CPU, it will be interesting to see what compromises they have to make to fit BB10 on the Playbook.
