Some of the guys points are a bit off.
'This thing boots up in less than 15 seconds, ready to go. My i7 iMac with 8 GB of RAM takes something like 2 minutes. My i7 MacBook Pro takes at least 30-45 seconds, and it has an SSD drive.'
My MBP takes around 15 seconds to boot, which wouild lead me to beleive his is running extemely slow, not really a fair comparison.
'Applications seem to load quicker. Files transfer quicker. The thing shuts down in about 3 seconds.'
Again, sounds no different to my MBP.
'Speaking of battery life, again, this thing shines pretty nicely in that category as well. Apple says it will get 7-hours, and based on my usage, that’s close. I’m usually seeing between 5 and 6 hours depending on what I’m doing and screen brightness. A couple times I have gotten about 7 hours.'
Same applies...
If his MBP had been running at 100% health I imagine he wouldn't have noticed any difference apart from the obvious thinner design and lack of backlit keyboard.
