The lithium-ion battery in this thing will be toast long before the lasers dim, but 10,000 hours is a relatively low bar. I'm still using a 5-year-old laptop, with no component replacements (other than the battery, and an SSD I installed shortly after buying it) and it still works fine. I know that batteries wear out in use, and expect that. Not everyone does. I did not know that laser diodes wear out that fast, and I'm glad to have the information.
