Not one of those lawsuits that would shut down the BlackBerry network -- RIM had to pay the devil (half a billion) to get away from that. I think this is just a tiny parasite in comparision, and we all know RIM has even bigger pockets now.
As for touchscreen, I think it's a good move, provided they don't alienate QWERTY and SureType users. While I hate the Windows Mobile touchscreens, I do like the innovations found in the iPhone touchscreen -- its web browser is truly first-class, with a number of very useful innovations.
I envision RIM expanding their gamut of devices: QWERTY, SureType, and touchscreen. Also, it may even have a roll-up keyboard -- RIM has a patent for a touchscreen device with a pull-up keyboard.
