AOG The Sky NowTV at £10 is an absolute bargain. You get access to BBC iPlayer, 4oD and Demand 5 though, which are burnt into the firmware alongside Sky News. Some say it's a stealth device, designed to sell you Sky content but only if you want it.
If you want more it lets you watch Sky's sport and movie channels without a bulky Sky box. Movies cost £8.99 a month, which is less than the price of a new DVD -- not to mention most cinema tickets -- and you can buy into sports event-by-event, for £10 per day. But you don't have to.
