Hi all, I'm about to replace my mid-2010 15" MBP and am looking at getting the 15" rMBP as my work machine. One of the main problems I'm having with my current MBP is that the battery is only at 81% capacity (5593/6900mAh) after 625 charge cycles over 31 months of use. I thought these non-user replaceable batteries were supposed to last 1000 cycles before reaching 80%...but anyway, there are other reasons I need a new work laptop. The souped up 15" rMBP with 768gb SSD and 16gb RAM is $3189 as a refurb from Apple, or $3499 at MicroCenter, new ($3749 from Apple directly I believe). If I went with the refurb, should I have any concerns with the SSD or battery since they both wear over time? I'm more worried about the SSD than the battery since even at $199, getting the battery replaced by Apple a year from now or less is still cheaper than the difference between refurb and new. The 768GB SSD on the other hand would be a bit more expensive. Thanks!
