Lenovo IdeaPad Slim 3x
$251 under the $800 cap
The best all-round Windows buy under $800 across 11 tested sources — 16 GB, 512 GB and a class-record 16 hr 29 min battery, at $549.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It runs Windows on ARM. The Snapdragon X chip is what buys the 16:29 hr battery, but legacy x86 software — niche STEM tools, older utilities, some games — goes through emulation and can stumble. Check your program's required software first. The display and speakers are also mediocre, and the GPU is weak for gaming.
Dealbreaker? The x86 ASUS Vivobook 14 removes every emulation question for $20 more ↓

Traps — this verdict avoids
Why the Lenovo IdeaPad Slim 3x is right for you
It avoids every trap below — and for just me, 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.
