I've been diving into the MacBook theme, experimenting. Recently, I bought a wonderful 2012 Retina model, but it became clear that I need a more powerful tool. I've been exploring used devices and came across 2017 model in good condition with a healthy battery - an i7 @ 2.9GHz, 16GB RAM, 512GB SSD, Radeon 560 with 4GB VRAM for $465. I'm considering purchasing it and selling my 2012 model. However, concerns about flexgate and the keyboard have been bothering me. Is flexgate an unavoidable issue? If I avoid fully opening the screen wide, will I be safe? As for the keyboard, if I keep it clean and use compressed air, will that be sufficient for ensuring its longevity?
