I know everyone is probably sick of these questions, but after poking around, they seem to vary enough from situation to situation not to be completely redundant. Anyway, here goes... I have a mid-2010 iMac 21.5, just exhausted Apple Care in August. It seems to chug along quite well, no problems. BUT it's 3+ years old. Connected to it I have a OWC Mercury Elite-AL Pro hard drive, for Time Machine backups. It is also 3 years old and has likewise been trouble-free. BUT it's 3 years old. Now, I know that all hard drives eventually fail. And the one in my iMac is 3+ years old. And the one in my Time Machine drive is 3+ years old. I have come to feel from my years of experience with Windows machines (HP, Dell) that 3 years seem to be a sort of watershed point in the lives of computers. Therefore, I am somewhat concerned. I spoke with Apple Support and explained my situation, which is that my iMac has exhibited no signs of distress, and I would prefer not to replace it until it does. But that I was concerned about not losing all my stuff (as as happened before). I asked for advice, and he suggested that I get a Time Capsule to replace my current wireless router (a Netgear WNR3500L which is also 3 years old, but seems to function fine, doesn't drop connection, ever) and Time Machine drive, so that I'll be covered until/when the HDD in my iMac starts to act up/die. So that's what I am considering doing. HOWEVER, I'm wondering whether a new Time Capsule would be inherently a better choice than a new OWC external drive, especially since my wireless router seems to be doing just fine, thank you. A new 2T external OWC drive like the one I currently use would be less than $200, a Time Capsule would obviously be more, and is a router to boot. But do I need a new router? Routers have no moving parts, and I'm wondering if and how they deteriorate? And I have read reports of problems with Time Capsules (not the drive, but the power supply dying after a year or so). Or should I just replace everything and be done with it? (Which would hurt---I don't want to spend money just to spend it). If I could get another year out of my iMac, which is my first Mac and by far the best computer I have ever owned, I would like to. Sorry to be so long-winded, but any suggestions would be more than welcome. Thanks.
