■ The catch — co-equal billing, always
The 16 GB is soldered forever. There is no slot, no service upgrade, no path. If your work grows into 32 GB — large Docker stacks, data science notebooks, several VMs — the only fix is buying another laptop. And there is no CUDA GPU here at all, so model training stays in the cloud.

Traps — this verdict avoids
Why the MacBook Air 15-inch M5 is right for you
It avoids every trap below — and for just me, no budget cap, it is the pick because it delivers:
Soldered RAM
Only 4 of these 11 laptops — Framework 13, ThinkPad E14, ThinkPad T16, Acer Nitro V 16 — let you add memory later. On every MacBook, the T14s, both Zenbooks and the XPS 13 the RAM is soldered for life. Buy the memory you will need in year four.
Lab-max battery claims
Advertised runtimes are manufacturer maximums. Real development work — compiling, running servers, driving external monitors — returns 60-75% of the rated figure. Tom's Hardware measured the 13-inch M5 at 15 hrs 37 min against a 15-18 hour claim.
Marketplace markup
ThinkPads and Frameworks are direct-buy machines. Lenovo configures a 32 GB/1 TB T16 Gen 3 at $1,029 and promos the T14s Gen 6 to roughly $1,499; the identical builds list at $1,859 to $2,599 through third-party Amazon and Newegg sellers.
