I wonder how long it will be before Apple prevent after purchase customization at all.
OWC $142 Apple $300
Apparently the SSD in the retina models is upgradeable but only to PCI based SSDs
The only downside is on Linux you have to reboot if you unplug the ethernet, but apparently that's being improved in 3.15.
RHEL 7 will be a problem then, I assume, as it seems to be based on 3.10?
At which point the SSD and Retina display sound nice, but that other stuff seems like it's going to a pain in the neck on a daily basis.
Remember when the iMac was the first USB-only computer, and had no floppy drive? Both were really unpopular at the time.
(Lack of Kensington is stupid though, I'll agree on that.)
Although the fact it's Apple-made is probably more important, since they'll have made sure it works.
Allowing the product line to evolve and fit all the little niches crevices is not Apple's style.
