I'll be picking up a new 15 Retina MBPro tomorrow and am considering whether it is worth getting the extended warrantly. What do you think?
DIGLLOYD: For expensive items, AppleCare is a good value. For laptops, which are far more prone to incidental damage, AppleCare is all but mandatory if you plan to keep the unit more than a year— something is likely to have a problem within 3 years.
Deals on Applecare
B&H Photo has excellent prices on AppleCare for Macs, iPads, etc, at significant discounts to what Apple charges.
I link to various AppleCare plans on my Computers Gear Page.
For the MacBook Pro 15" Retina, I presume that the $244 Apple 3-Year AppleCare for 15" & 17" MacBook Pro is the right one.
