Performance scores
Buying remaining runtime, not capability
The Lenovo B570e is a 2011 machine asking $120 against a $248 class median. Its Pentium B940 and 8GB of memory belong to the opening act of the last decade, and the measurements say so without cushioning: graphics at the data floor, a reliability index of 1 against a class median of 54 — the lowest band the catalog tracks — and a performance index of 2.96, over 93% below the class middle.
What a 2011 entry laptop is for
Fifteen years of progress have converted this class of hardware into a fixed-function tool: a text editor, a browser for light pages, a machine for one thing at a time. The 8GB of memory — an upgrade well beyond its original spec — keeps the floor from being absolute, but nothing on this chassis competes with even today's cheapest new silicon.
The reliability reading is the verdict
An index of 1 does not mean the machine will fail tomorrow; it means the odds it beat to still be running are the whole story. At this price and age the purchase is explicitly a bet on remaining runtime — spare-parts economics, a backup machine, a specific single purpose — not an investment in capability.
Price trajectory
From a $900 anchor the machine has settled at $120, decaying at 6% per year with a two-year projection of $106. The curve is nearly flat at this altitude — the value was in the hardware when it was new, and the remaining price is a rounding error on that history.
Against the alternatives
The neighborhood is crowded with peers from the same era: Lenovo's own 100-15IBY at $108 and IdeaPad G575 at $110 below, Dell's Inspiron 15 3542 at $123 and the IdeaPad Z575 at $122 alongside, HP's 17-p023ng at $137 above. Equivalent hardware, equivalent odds — pick on condition, not on spec.
Bottom line
A budget-friendly pick only under one honest framing: this is a utility purchase of remaining runtime. Anyone shopping for capability should spend more — meaningfully more — because at $120 the capability on offer is 2011's entry tier with a reliability index of 1.
