If they could just bring the features to what they already have...they think the trackpad is going to save them? Just bring back my custom profiles for pete's sake. 10.2.1 is close but it's not quite there yet.
When BBM came out cross-platform, my reaction was "who cares?" But I have it on my iPhone and it's really pretty great, especially delivered/read indicators. It was always fast on BlackBerrys and I'm happy to see it's also slick on other devices. Clean interface too.
