At the end of the day, BlackBerry (and other manufacturers) compare their tablet to the iPad 2, and try to point out the places that theirs is better. Apple don't need to do this, they created this market.
Mmmmmm
The market was around a long time before ipads arrived, its just no one wanted them. With the rise in social media, they now have a use where as before the most you could hope for was a cut down version of windows running email and show off your holiday snaps. All Apple did was pimp their iphone and generate a new interest in tablets, thus proving Apple could stamp their logo on a porceline poo and Apple users would queue through the night to be the first to own one!
It's natural for manufacturers to point out how there's is better, but how do Apple respond. By throwing every toy they have out of the pram and taking them to court. I'm thinking of the recent Samsung Galaxy S2 v Apple iPhone case where Apple were upset at them releasing a faster, better phone without them knowing about it so took them to court accusing them of copying their design for the iphone! Hilarious, as the samsung is larger and looks nothing like an iphone!
At the end of the day there are 2 main markets for phones, mp3 players and tablets. We have Apple, and everyone else. The problem is Apple won't share with the rest of the market so the rest of the market is sharing with itself and growing at a very fast rate. In a world when it's important to share information if the two markets can't speak to each other the smaller market will eventually fade away! I can already here the Apple users grand kids asking, what's an iPad Daddy?
