Performance scores
The magnesium flagship: three top-quartile readings, one mild flag
The ExpertBook B9 OLED (B9403) of 2023 asks $886 with a Core i5-1335U and 32 GB of RAM, and its data is the balanced-business archetype: reliability at 70 — 64.7 percent above the business-class median of 42.5, top quartile; mobility at 90 — 50 percent above the class median, top quartile; and compute at 75.15 — 41.9 percent above median, also top quartile. The single flagged weakness is mild by this shelf's standards: the 32 GB memory ceiling runs 20 percent below the class median of 40, and even that reads in the pro tier.
The balanced trifecta
Three strengths, all top quartile, none extreme: that is the B9's whole personality. The magnesium chassis is the lightest business body ASUS ships, and mobility 90 is its receipt. Reliability 70 answers the buy-it-for-years question. Compute 75.15 from the 1335U covers every office workload with headroom. No column collapses, no column dominates — the machine simply places high everywhere a business buyer measures.
The one flag, in proportion
Memory at 32 GB against a class median of 40 is the lone weakness, and it deserves its proportion: a fifth below the norm, pro-tier in absolute terms, and unremarkable for an ultralight flagship. The capability sheet is empty — no gaming claims made — which fits the machine's contract exactly: this is a working document-and-call machine, not a receipt-backed entertainer. The OLED panel completes the working-day case.
Gentle flagship decay
The measured rate is 10.62 percent per year with no unit anchor. Two years retain roughly four-fifths of the $886. Premium business bodies with triple top-quartile readings are the canonical hold-value profile, and the slope prints it.
Positioning on the shelf
No analog peers are returned. The batch's $886 row has carried business iron before, and this seat's distinction is balance: where the ExpertBook B5 triplets lead on reliability and compute but blank the graphics, the B9 spreads its strength across all three carrying axes.
Bottom line
For a buyer who wants the light flagship that does everything office-shaped well and nothing badly, this is the archetype ticket: mobility 90, reliability 70, compute 75, an OLED panel, and a memory flag small enough to state in one clause. It is the least dramatic and most defensible business purchase on this shelf.
