Inspiron 5391: a Premium-tagged ultrabook whose performance column never got filled in
The Inspiron 5391 carries a Premium preset tag in the ultrabook class, and its chassis-level numbers honor that promise: this is one of the more portable records in the batch. But the performance side of the sheet is empty, which makes this a buy-on-chassis, verify-on-hardware kind of listing.
Where it holds up
Mobility is the claimed strength and it is a convincing one: 95 against an ultrabook median of 64, a 48.4 percent advantage that puts the machine in the top quarter of an already portability-focused category. Portability agrees at 83.8, a high-band reading — the two measures tell the same story from different angles, which is what you want to see in a thin record.
For a used buyer, that pairing is the whole value proposition: this is a carry-everywhere form factor, and the sheet supports it twice over.
Where it falls short
The overall performance index reads zero against a category median of 41.72 — an empty reading rather than a measured result, since no processor or configuration data was captured for this record. The graphics column is likewise zero, a coverage gap rather than a measured zero. The composite score of 3 reflects those blanks more than any verdict on the hardware itself, and every task axis sits at the low-band floor (gaming 19, modeling 12, CAD 19, photo 13) common to unmeasured legacy sheets.
The honest summary: portability is proven, capability is unproven on paper.
Price and depreciation
No listing price is recorded for this configuration, and no depreciation curve is modeled — there is no resale math to quote.
Alternatives to consider
Within this batch, the Inspiron 7370 offers the same empty performance column with slightly lower portability (74.2), while the 7380 pairs the same blanks with 77.2 portability. A buyer who wants actual measured numbers in an ultrabook shell would need to step outside this legacy group entirely.
Bottom line
Fairly priced for the class, the Inspiron 5391 is a Premium-badge ultrabook bought for its proven carry credentials — top-quarter mobility and high-band portability — with the explicit caveat that its performance sheet is unmeasured and must be checked against the actual unit before money changes hands.
