Lenovo IdeaPad Slim 3i 15
$370 under the $800 cap
The shared homework machine — a full 15.6-inch screen, Microsoft 365 included, and safe stock at $430, the lowest-risk budget buy across 11 tested sources.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It ships 8 GB of RAM and a 128 GB SSD. Both budget listings quietly downgraded from the 16 GB / 512 GB builds that sold at ~$350-$380 in spring, and neither is upgradeable in practice — 128 GB fills fast, so plan on cloud storage or a $40-$60 external SSD. Battery is ~8 hours, roughly half the Slim 3x's tested runtime.
Dealbreaker? The Slim 3x doubles the RAM and quadruples the storage for $119 more ↓

Traps — this verdict avoids
Why the Lenovo IdeaPad Slim 3i 15 is right for you
It avoids every trap below — and for family of 4, no budget cap, it is the pick because it delivers:
Cap creep
Three picks that used to fit have blown past the $800 line: the Lenovo IdeaPad Slim 5 16 is up ~24% to $828, the OLED Lenovo Chromebook Plus 14 lists at $1,009 against a ~$649 MSRP, and the M4 MacBook Air is clearance-only at ~$894. Check the live price, not last term's reputation.
Quiet config downgrades
Budget listings keep the model name and drop the specs — the Acer Aspire Go 15 and the Lenovo IdeaPad Slim 3i both now ship 8 GB / 128 GB where 16 GB / 512 GB builds sat at ~$350-$380 in spring, and the 16 GB Aspire Go is a separate SKU at ~$619. Verify RAM and SSD on the exact listing, not the model name.
The OS your degree can't run
3 of the 12 machines here run ChromeOS or Windows-on-ARM. ChromeOS cannot run Adobe Creative Suite, MATLAB or AutoCAD at all, and Snapdragon X laptops run legacy x86 software through emulation. Check your program's required-software list before you pick an operating system.
