T14 are a refresh from the T480; slightly more modern hardware and there are AMD versions. still durable, good build quality, more power efficient, and inexpensive as the market's flooded with corpos ditching their old devices and switching to Newest & Best.
expandable, repairable with cheap parts that are somewhat cross-model/generation compatible, you can't go wrong there. besides, it's always good to be couple gens behind for the best linux hardware compatibility.
