I just don't like glues. Something about it in our expensive devices ticks me off. It is NOT because of user-replaceability or upgradability concerns. It's just that I used to think of my old MacBook pro (2006) and Mac Pros as a well-designed mechanical watch or high-end audio components where everything is tightly engineered and assembled. Apple devices nowadays just don't have that feel anymore. Feel more like a disposable gadget. At the end of the day it doesn't matter. I'm just reminiscing of the good old days . I'm not sure if I share this feeling with anyone out there.
