There is an App World as pointed out, with some variety of products too. The Store though is not as extensive as that of IOS or Android and could do with some work.

The Bold is one of the best smartphones I've ever used but there is lots of truth written here. While I haven't fully explored OS 6 or 7, it feels clunky and slow (awkward even) Vs the aforementioned alternative platforms. The browser is also one in need of a total overhaul. In fact, few know the BlackBerry browser uses webkit like Google's Chrome but that might be where the similarity ends. Whereas Google's product is lightweight, fast and secure, the BB browser can feel quite slow.

Touch might be one area RIM needs to explore, as is use of virtual keyboards to free up screen real estate. The other might be more memory (an issue I've read RIM is reworking in future models). I however think a total overhaul of the software platform (e.g. OS 7 and QNX) is what will ace it. That, coupled with the Berry's famed security (encryption) will be a key selling point.

Overall it's a sad read about a magnificent product.
