The answer — one pick, priced
Get the
ASUS Chromebook CX15
no budget ceiling
The only pick here under $300 — 15.6" FHD, 8GB/128GB, MIL-STD 810H toughness and, across our 13 sources, as long an update runway as anything on this card: June 2035.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It is not Chromebook Plus certified. No Gemini in ChromeOS 144, no free 12 months of Google One AI Premium, and the Celeron N4500 with 128GB of eMMC is adequate for browsing, Docs and streaming and no more. It is also 3.51 lbs — the heaviest machine on this card. If anyone in the house wants Android plus Linux apps and 20 tabs open, this is the wrong buy.
Dealbreaker? Runner-up №1 adds Plus certification and 512GB for $130 more ↓

Traps — this verdict avoids
Why the ASUS Chromebook CX15 is right for you
It avoids every trap below — and for family of 4, no budget cap, it is the pick because it delivers:
The AUE cliff
ChromeOS auto update expiration is a hard end-of-life, fixed by the model rather than by when you buy. Across these 11 picks it spans June 2032 to June 2035 — the ASUS CX34, Samsung Galaxy Chromebook Plus and Acer 516 GE have only about six years of updates left.
The config is the machine
RAM and storage are not user-upgradeable in a Chromebook, so the box you buy is the box you keep. 4GB configurations cap out at 5-10 browser tabs and cannot run Android plus Linux apps comfortably; 8GB is the floor for real multitasking.
Amazon is no longer the price
Three of these 11 models had no live new-condition consumer Amazon listing in July 2026 — only Renewed, Business-gated or unavailable entries, while the brand stores stocked them normally. Where only third-party stock exists the price disconnects: the ASUS CM14 Flip's sole listing is $499.99 against a ~$329 list price.
