After the remaining stocks get depleted, price increase of minimum 100$ USD expected due to memory shortage on AI Boom. There is unprecedented spikes in memory prices—rising nearly 95% in early 2026 alone, and over 300% since 2025.
S5 won't be discontinued for few more years(except the 9" version which will be discontinued once the current motherboard stocks get depleted).
Standard version is not affected by this shortage.
