The case I had on my MacBook Air had hundreds of small, round perforations by design. I recently removed it after almost six years because the bottom had cracked and was beginning to separate. After cleaning the computer with a soft rag, the metal surface looked just like it did when it was new, with no scratches or dents. Although I took good care of it, the MBA has traveled with me extensively, including several trips to the middle east.
Sleeves are great—I have a bag (Waterfield Designs calls it a SleeveCase) that I used to carry my MBA and now my MBP. But at some point you have to take the computer out. I like the hard shell because it protects against scuffs and dings that can happen when handling the laptop.
Agree with you 100% about the hardshell offering better protection.
I know the office jockeys do not like them, but out innreal world , protect much better.
I used the iblasion on my mac book air, went thru about 6 a yr as i am a mechanical cont. and take mine everyday on Jobsites, getting muddy ,scratched, etc.
I upgrade every cycle and give my old one to my grandaughter. They look very good after taking the case off.
On my new mac book pro ntb i bought this one - the brown one and feel it is a much better fit and case than the iblasion cases.

I also have recieved many compliments and inquiries on it taking on construction sites daily.
I just ordered 2 more as they get battered up pretty good but protect very well.
Overall , best case i have had since my first 2011 macbook
