Hi Everyone, First post, but long time daily reader. Short Version: How reliable are MBP hard drives, and their other critical components? Long Version: I'm a self employed web developer/business owner who works primarily in the photography and video field. I'm a long time PC user, but am thinking about making the switch. Presently I use a 3yr old home-built PC which is fairly powerful and extremely reliable. It's nothing special: 2x monitors, 2x500GB raided HDs, 8GB ram, dual core 2.8ghz. Although I'm very happy with it, given my line of work I like to upgrade my main system every few years to minimize the chance of unexpected failure. I also have a 2005 IBM Thinkpad as a laptop. The thing is ridiculously underpowered for anything beyond YouTube and email, but the original battery still lasts an hour and the machine runs quite well. I've literally taken it around the world twice and it's never once let me down. (12" screen, 2lbs) Although it's not well suited for my current work, and for that reason it mostly collects dust these days. Both of these computers need to be replaced soon. And while I like desktops, I really miss the flexibility of easily taking my work with me, even if it is just on the couch or a coffee shop. I was thinking about getting a 15" MBP, with as much ram, storage, and processing power possible. Whatever the top of the line model is for that size. I was going to buy in January, but will wait for Sandy Bridge - as I'm not in an urgent rush. My hope was that this could be my main machine. I'd buy a Henge Dock (when they come out) and have it hooked up with my keyboard and two monitors (via USB external display), and other peripherals. But then I'd have the flexibility to pick it up and take my office with me when needed. I am hoping that the machine would be powerful enough for my regular workflow (a lot of applications open, Photoshop, short video editing). However, my concern is that the computer has to be extremely reliable. While I do backup obsessively and take care of my gear, the possibility of being without my primary machine for any period of time could be extremely costly. I have had a shocking number of friends who have all had their Macbook hard drives go bad. (75% of them have had a failure at least once) I'm not sure if this is more to do with the nature of laptops, or just bad luck. How reliable is a MBP? Are my friends just unlucky to have a high proportion of hard drive failures? Would you consider it as reliable as any other computer for mission critical tasks? What is the usable lifespan on most MBPs? Thanks in advance!
