My thoughts:
- Plastic will warp when heated.
- The metal in the MBP is probably being used as a heatsink
- It won't look good.
There are two contradictory things about Macers:
(1) They hate macs. They are always complaining about their computers, about how they waste time hanging around the "genius" bar. (e.g. maybe it is not smart to do!)
(2) They insist on buying macs no matter what and won't consider that you can get plastic computers, computers with good heat sinks, computers with more RAM, computers with NVIDIA graphics cards or AMD APUs, etc. if they just were willing to take their business elsewhere.
Apple service isn’t as nice as it once was as they have scaled, but 8/10 times you can talk face to face to an accountable individual to resolve issues with service.
Try dealing with PC companies — it’s just a worse experience by any metric.
There are definitely downsides with respect to cost and some particular capabilities.
