I haven't bought a new MacBook in so many years, but I'm now thinking of buying the new 2017 MacBook or MacBook Pro. However, before I do I've a couple of questions: Last time I checked, one was not supposed to use a MacBook in bed or on a pillow (as advised in https://discussions.apple.com/docs/DOC-6341 ) because of blocking the circulating air. Does that mean that no longer applies, because the new MacBook has no fans? Can I just go ahead and use my MacBook while tucked in bed as if it's my iPad/iPhone (or hold it on my lap) without risking overheat? Or is it still not advised to do so? For example, would I be able to edit a video on Final Cut Pro while watching a tutorial video on YouTube, holding my MacBook on my lap/pillow/in bed, or would it be too intense of a task? Also, are cooling pads still necessary? Have MacBooks reached the state where they're dustproof like iPhones? If not, how often does it collect dust inside and how often should I disassemble it and clean it? Is cleaning it a service covered under warranty? Thank you for your time.
