Digital SLR cameras have long rivaled their old-fashioned film-based cousins, but a short time ago they have been winning the upper hand more and more as technology advances day by day. Ease-of-use had consistently been the main appeal of digital SLR cameras, but now the amount of control has reached unprecedented levels, such that the only reason to go with film is for the resolution. But improvements of late appear to be erasing even this benefit, and breakthroughs are just around the proverbial corner that should make digital the route for the vast majority of professional photographers to embrace. In a sense, film will always be superior, but it will in all likelihood be only marginally so, and on balance not as cost-effective.

Bluetooth headsets allow hands-free usage of audio even while engaging in other activities. Lots of mobile telephone users sport such headsets while driving a vehicle, walking, shopping, eating. Several Bluetooth headsets even form an crucial component of such activities, such as videogaming, providing for an immersive you-are-there feeling. Oddly, the one great common activity for which Bluetooth cellular technology would be ideal has yet to be satisfactorily put in place – exercise, where most kinds of which call for some measure of sweating for which designers and vendors have yet to find the best solution! Still, the models specifically designed to go with exercise that are available are workable enough if one considers them to be disposable.
