I just don't see what they could do to redesign it, make it thinner? Thats just an air, and I highly doubt they're going to go with SSDs being baseline because big ssds are expensive. Not everyone wants to carry around an external enclosure and cables, defeating the purpose of a laptop.
I'd say the chances of a redesign are minimal unless for aesthetics (e.g a new material or finish/colour/other **** like that)
It's fully functional and is already at the limits of portability, power, heat dissipation and all.
The current design is fine. It's still revolutionary I'd say..
I should think these forums exist for asking for advice when in doubt, or discussing relevant and current products and benchmarks.
Not asking questions that are impossible to answer because no one has the answers.
