Ok, scrub that, a bit more research shows it's a bad thing potentially as it means apps are no longer 1 off purchases and will require further staged payments to update them or, as in the case of the F1 app, keep it relevant to the current race. They do give the British GP as part of the initial price, and the software looks amazing, but £5 for one race is too much, especially when you can get the info for free if you just surf the F1 sites with Safari.
