I just did a comparison. A 16 GB upgrade with lenovo is $1,060 for DDR3 pc3 12800. With apple 16gb is 200 on the retina. Granted its soldered on. While I see your point, a priced out lenovo from the manufacturer to equal the specs i have right now is clost to 2.8k
I already bought one to test and was incredibly disappointed. Given the SSD, I would have thought it to be super quick, but it is sub-par to my dell d630..really.
Also if I price it out, it equals a T530 or W lenovo with specs. I would buy ssd and ram externally from newegg
I had been looking at Lenovos, but when i saw they charged 1k for 16gb of ram, when you could buy the same ram on newegg for 120, I stepped back quite a bit.
All of our production servers run centos, and it makes it easier to just run the same system and use nx/nomachine for compat reasons. I have not had the chance to play with fedora yet though.
I have been using Centos 6 for primary when doing web related items, but would prefer something more user friendly with wider support. It seems to boil down to these choices right now: Centos, Ubuntu, or Mint. What have you been using?
