well u knw globally all the laptop prices have reduced, so to compete with other vendors one has to use similar kinda material which others use, u see, HDD,MBD,Proc,Mini pci cards are all made my same companies who also supply to HP,Sony, and other vendors, i dont see anything different with selection of parts, if Dells selling u a product apart from chassis, logo and service contract, rest all components are made my same companies across all laptop manufacturers, and i hardly see why Just dell is being highlighted, HP has Crappy service, before shifting to dell owned a notebook and they Suck at even Sucking the service, u may call it location specific, but i always had traveled with the notebook, atleast Dell doesnt keep u in dark like others did with Nvidia issue, and hence Dell replaced most of the notebooks motherboard which has stopped now cos Dell wont be using Nvidia gpus now apart from Alienwares, My old hp laptop which i owned , was globally eligible for notebook Motherboard replacement which they denied in india and sooon after warranty ended i started having issues as per symptoms for motherboard replacements, theres nothing called cheap or high quality parts ...... all use intel / AMD procs, foxxconn / intel mobos, batteries by sanyo / sony, HDDs by hitachi, fujitsu, WD, seagate, Rams by Hynix/Kingston same graphics chipset hope things are clear now on what im trying to say, its after sales service and configuration which matters and not brand (BTW brand is nothing but a reputation for what kinda service they provide , which again is aftersales), hope my logic is clear, i dun wanna disclose what i work as or what i do to have this industry Gyan, But this is what it is
