Apple has been suing everyone over everything recently. It just shows how desperate they are. Rather than try to keep up, they'd rather keep under-updating so they can over charge for tech that they know they are going to make obsolete (but not by much) the next year.
I won't say anything about them being over-priced, because to be honest, their phones and iPads are quite reasonable, but the way they've been suing over little things recently is just kind of sad. It's like "Oh, they have a glass screen that you can touch?! That was our idea!"
