IdeaPad 100S-14IBR — a 1.4 kg featherweight built around a slow heart
The IdeaPad 100S-14IBR (2015) was Lenovo's ultra-cheap light laptop: a Celeron N3050 dual-core at $135 today, against a $248 class median. The measured profile is the classic floor-featherweight split: its one strength is weight at 1.43 kg versus a 1.8 kg class median (a "light" placing), while performance index reads 1.64 versus 43, CPU 3.28 versus 59, and graphics zero versus 27. The N3050 is among the slowest x86 parts in the volume catalog.
What it does well
The weight is real: at 1.43 kg the 100S was and is genuinely easy to carry — the measured strength is the machine's identity. For a single-purpose portable — notes, email, light browsing, e-reader duty — the portability argument holds. The chassis was surprisingly pleasant for the price tier.
The trade-offs, stated plainly
Everything else is the price of that weight: the CPU floors the catalog, graphics is zero, and multitasking beyond a couple of tabs will test patience. No gaming claim survives the data. At $135 the machine is near terminal value — the purchase question is whether any workload exists that is light enough for the N3050 and heavy enough to justify a laptop at all.
Price trajectory
From a $900 launch position it has declined at about 7.6% per year to $135, with a projected $115 in two years (15% further). The absolute drop is $20 — disposal-stage pricing.
Against its neighbors
An HP Pavilion G7 at $145 and a Lenovo V145-15AST at $149 sit above; a Dell Inspiron 15-3552 at $127 and an HP 15-ay087ur at $120 below. The neighbors are all in the same performance basement; the 100S's only differentiator is the lighter chassis — if portability is not the point, the V130-class machines with real Core CPUs are worth the stretch.
Bottom line
Worth its price strictly as a featherweight for the lightest duties. The 1.43 kg frame is the product; the N3050 is the tax. Buyers not specifically chasing minimal weight get more machine per dollar elsewhere in this band.
