Performance scores
A pen convertible at exactly the class-typical price
The ThinkPad X390 Yoga from 2017 asks $358 — a rounding step from the convertible-class median of $356. Inside is a quad-core Core i5 8250U with a 32GB memory ceiling. The measurements place it soberly: CPU at 35.89 against a 59.6 class median, graphics at the data floor with no discrete card, and reliability at 20 against 49. Nothing here is a steal; nothing is a trap.
The form factor is the product
The X390 Yoga's pitch is the 360-degree hinge, the ThinkPad pen support, and the 13-inch carry weight in a business build. For note-taking, marking up documents, and presenting, the convertible format earns its keep in ways benchmarks do not capture. The quad-core chip keeps the pen-and-ink workflows and everyday office loads moving without drama.
The honest limits
Graphics at zero is the integrated-only reading — no game gates pass, and visual work beyond photo management is out of scope. The reliability index of 20 against 49 is the axis the verdict flags: convertibles live harder lives in tablet mode, hinges and screens take the wear, and an eight-year-old unit deserves a hands-on inspection before purchase.
Price trajectory
From a $1,500 convertible anchor, the machine has decayed to $358 at 8.54% per year, with a two-year projection of $300 — a further 16% drop. Buying at the class median means the market has already priced in both the format and the age; the curve from here is ordinary.
Against the alternatives
The neighborhood is well-stocked: HP's EliteBook x360 1040 G6 just above at $381, Lenovo's IdeaPad Flex 5 14ARE05 at $403; the ThinkPad X1 Yoga 4th gen and Dell's Inspiron 15 7573 below at $313–333. The X1 Yoga at $333 is the direct rival — newer premium lineage for less money, which makes condition the tiebreaker.
Bottom line
Fairly priced for the class. The honest framing: this is a pen-first business convertible with quad-core office speeds, a generous memory ceiling, and an aging reliability reading. Buy it for the format at a fair price — not as a performance play, because the measurements will not support one.
