Munster estimates that "Apple Glasses" will initially be priced at $1,300. That price point might limit early demand, but like all emerging technologies, costs are high initially but come down rapidly over time -- Munster expects average selling prices to decline to $1,000 by 2022 -- spurring adoption in the process.
As far as avoiding the same mistakes, one important step that Apple is taking is releasing ARKit for iOS well in advance of Apple Glasses. This helps Apple build a pipeline of AR content, starting with the iPhone. You can be confident that once Apple Glasses are ready to launch, Apple will make it easy for developers to bring existing AR apps to Apple Glasses (Google Glass was lacking on the content front, as there were only a few dozen third-party apps).
Apple has taken note of the importance of aesthetics when it comes to wearables, which is why it offers such a wide array of Apple Watch configurations to cater to diverse consumer preferences. Additionally, industrial design is one of Apple's greatest strengths. It's not clear what the optimal interface for AR glasses should be, but Apple also has a strong track record in this department; each of Apple's game-changing products were built on revolutionary new interfaces.
