I find myself using fewer and fewer applications on my phone these days. Whatsapp to occasionally check a thread I have going with some friends, and the odd game of Solitaire.
Bought so many games on my WP7 but I just don't have the time to really play them. I know "apps" are the buzzword right now, and I know some are well made, but I just don't see how anyone has time to use them. I suppose it'd be different if I were using an iPhone or something, where most of the functionality is lacking from the OS itself and bolted on with applications.
