Performance scores
The Education Tank: Mobility 99, Everything Else Negotiable
The Dell Chromebook 3100 is a ruggedized education Chromebook with a Celeron N4000, and its sheet is dominated by one number: a mobility reading of 99 against an ultrabook-class median of 64 — top quartile by a wide margin. No listing price is recorded.
Where it holds up
Mobility is the flagged strength at 99, and portability backs it up at 91.3 in the top band — this is a machine designed to be carried by people who drop things. Gaming reads 23, modeling 12, engineering CAD 19, and photo design 14, all low band: honest numbers for a fanless Celeron.
Where it falls short
The performance index reads 1.55 against a class median of 41.72 — low band, 96% below median — and it is the flagged weakness of the record. There is no GPU entry at all: a coverage gap rather than a measured zero. Composite capability reads 7 against a median of 49. Any workload beyond a browser tab set is out of scope for this hardware. That is the correct reading of a fanless education Celeron: built for one job, scored accordingly. The 23 gaming and 12 modeling readings are scale placements, not invitations.
Price and depreciation
No listing price is recorded and no depreciation curve is modeled for this entry — nothing to project from.
Alternatives to consider
The Chromebook 3120 in this batch trades a little portability (92 versus 91.3 is essentially even) for the same experience with 4 GB of recorded memory. Outside ChromeOS, the Inspiron 3502 (2021) at $399 is the modern budget-Dell answer with a mid-band office score.
Bottom line
Fairly priced for the class. As a disposable, drop-proof web terminal the sheet makes sense; as anything else, the performance index answers no.
