I've found that L and E series seemingly mirror the T line but with a couple of years of delay, so overall with time it gets worse repairability wise, but gets better with things like 16:10 screen aspect ratio.
I haven't researched the 2024 T series, is it noteworthy other than having some models with ram slots? Feels like some hype is going on. In any case, expect ~2026 L,E series to have similarly constructed models.
