Dell Latitude 3390 2-in-1 review

Latitude 3390 2-in-1: the other half of the measured flip pair

The Latitude 3390 2-in-1 completes this batch's near-twin flip set alongside the 3310 2-in-1: the same measured 16 GB sheet, the same mobility 81, portability of 72.1 against its twin's 72.4. Three-tenths of a point is not a buying criterion — condition is.

Where it holds up

Mobility of 81 against a convertible median of 68 — a 19.1 percent advantage, top quarter of the category — is the promoted strength, with portability of 72.1 in the high band agreeing within a rounding error of its twin. The 16 GB pool is the tier standard, and the interior is measured: performance 6.87, office comfort 20.6. In a batch where most flips are blanks, two written-down twins are a small luxury.

The sheet's argument: a known quantity in a proven carry format.

Where it falls short

Graphics is the flagged weakness at zero — a coverage gap rather than a measured zero, with no discrete GPU entry recorded. Office comfort of 20.6 is low-band, performance trails the convertible median of 37.38 by 82 percent, all four task axes hold the low-band constants (gaming 19, modeling 12, engineering CAD 19, photo 13), and the composite score of 7 trails the category median of 46 by 85 percent.

Measured, modest, and matched — the twin's verdict, verbatim.

Price and depreciation

No listing price is recorded for this configuration, and no depreciation curve is modeled — no resale math to quote.

Alternatives to consider

The 3310 2-in-1 is the twin — condition decides. Upgrades within the batch: the 5300 2-in-1's full 32 GB baseline (office 58.9, portability 76.3) or the 7310 2-in-1's take on the same generation (82.6). The blank-but-portable alternative is the 7285 2-in-1 at 97.5.

Bottom line

Fairly priced for the class, the Latitude 3390 2-in-1 is the second measured twin: identical honest numbers, high-band carry, and a decision that properly belongs to the units' condition reports rather than their spec sheets.
