Price band is the bucket the base config lands in: under $500 / $1000 / $1500 / $2000 / $2000+. Use the band filters to shop a budget. Kits and gaming machines jump bands with GPU or RAM upgrades — the Price detail spells out the config.
RAM / storage tags: Upgradeable means at least one config has an accessible SO-DIMM or M.2 slot; Soldered means what you buy is what you keep. Apple and most thin ultrabooks are soldered on both.
Linux — excellent/good = vendor-certified (Framework, ThinkPad, Dell Developer Edition, ZBook); fair = works with tinkering; poor = ARM Snapdragon or Asahi-only.
Budget and gaming battery Wh / weight / life figures are approximate — not always on spec sheets.
Build quality is a chassis-material read by product line — Full metal (CNC / unibody aluminium, magnesium, carbon-fibre: MacBooks, XPS, X1, Zenbook, Razer, Framework's deck), Metal + polymer (metal lid on a plastic base — most gaming laptops), Polymer (budget). Heuristic, not a per-SKU spec.
Touchscreen is inferred, not sourced per config: convertibles = yes, Apple = no, gaming / workstation panels rarely offer it, most Windows ultrabooks list it as a paid option. Check the exact SKU.
