I’ve always thought of TiVo as the Mac of PVRs. Great interface, intuitive controls, solid product. Yesterday, TiVo announced it would stop offering its lifetime service option, replacing it with one-, two- and three-year service commitments. Three years runs a hefty $469. As a lifetime service purchaser (service started in 2000, and is still going strong) and someone who’d been mentally shopping for a Series 3, this came as a blow. How much would I really pay for TiVo? Especially now that the mini line seems to be converging with my living room? Would I pay multiple hundreds of dollars for that wonderfully designed remote? For the great menu interface? Or is it time for me to start thinking Linux/MythTV? Dropping the lifetime service has probably turned me into a switcher. But am I switching in the right direction?
