Ngowe-1972, uAlan Kay, isazi sekhompyutha saseMelika, weza nengcamango yecwecwe (ebizwa ngokuba yiDynabook), awayichaza ngokweenkcukacha kwimibhalo yakhe eyapapashwa kamva. UKay wayenombono wesixhobo sobuqu sekhompyuter sabantwana esiya kusebenza phantse njengePC.

I-Dynabook yayinepeni ekhanyayo kwaye inomzimba omncinci kunye nomboniso weepikseli ezisisigidi. Iinjineli ezahlukeneyo zekhompyuter zicebise iziqwenga zehardware ezinokusebenza ukwenza umbono ube yimpumelelo. Nangona kunjalo, ixesha lalingekafiki, kuba ii-laptops zazingekaveli.

Ngowe-1989: Ixesha lezitena

Ikhompyuter yokuqala yethebhulethi yaqala kwintengiso ngo-1989 phantsi kwegama elithi GRidPad, igama elaqulunqwa kwiNkqubo yeGridi. Nangona kunjalo, ngaphambi koko, bekukho iitafile zegraphics eziqhagamshelwe kwizitishi zokusebenza zekhompyuter. Ezi cwecwe zegraphic zivunyelwe ukwenza ujongano lomsebenzisi olwahlukileyo, olufana noopopayi, umzobo kunye nemizobo. Basebenza njengempuku yangoku.

I-GRidPad yayingekho kufutshane nento echazwe yiDynabook. Zazinkulu, zinobunzima obumalunga neekhilogram ezintathu, kwaye izikrini zazikude ukusuka kwibhentshimakhi yepixel yezigidi zikaKay. Izixhobo nazo azizange ziboniswe ngokwegreyscale.

1991: ukunyuka kwePDA

Ekuqaleni kwee-90, abancedisi bedijithali bomntu (PDAs) babetha imarike nge-bang. Ngokungafaniyo ne-GRidPad, ezi zixhobo zekhompyutha zinesantya esaneleyo sokusebenza, imizobo efanelekileyo, kwaye zinokugcina ipotfoliyo yesisa yezicelo. Iinkampani ezifana neNokia, i-Handspring, i-Apple, kunye nePalm ziye zaba nomdla kwiiPDAs, zibabiza ngokuba yitekhnoloji yekhompyutha yokubhala.

Ngokungafaniyo ne-GRidPads eyayisebenzisa i-MS-DOS, izixhobo zekhompyutha zokubhala zisebenzisa i-IBM's PenPoint OS kunye nezinye iinkqubo zokusebenza ezifana ne-Apple Newton Messenger.

1994: Icwecwe lokuqala lokwenyani liyakhutshwa

Ngasekupheleni kweminyaka yee-90 imbono yenoveli yomfanekiso kaKay wethebhulethi yayiphelile. Ngo-1994, uFujitsu wakhupha i-tablet ye-Stlistic 500 eyayixhaswe yi-Intel processor. Le thebhulethi yeza neWindows 95, ekwavela kwinguqulelo yayo ephuculweyo, iStylistic 1000.

Nangona kunjalo, ngo-2002, yonke into yatshintsha xa iMicrosoft, ekhokelwa nguBill Gates, yazisa iThebhulethi yeWindows XP. Esi sixhobo sasixhaswe bubuchwephesha beComdex kwaye sasiza kuba sisityhilelo sekamva. Ngelishwa, iThebhulethi yeWindows XP ayiphumelelanga ukufikelela kwi-hype yayo njengoko iMicrosoft ayikwazanga ukudibanisa ikhibhodi esekwe kwiWindows kwisixhobo esisebenzayo se-100%.

Ngo-2010: Isivumelwano Sokwenyani

Kwaba ngo-2010 ukuba inkampani kaSteve Job, i-Apple, yazisa i-iPad, ithebhulethi enika yonke into abasebenzisi abafuna ukuyibona kwi-Kay's Dynabook. Esi sixhobo esitsha sisebenze kwi-iOS, inkqubo yokusebenza evumela izinto ezilula zokwenza ngokwezifiso, isikrini esichukumisayo esibonakalayo kunye nokusetyenziswa kwezandla.

Ezinye iinkampani ezininzi zilandele emanyathelweni ka-Apple, zikhupha uyilo olucingisisiweyo lwe-iPad, olukhokelela ekuzalweni kwentengiso. Kamva, iMicrosoft yenza izilungiso kwiimpazamo zayo zangaphambili kwaye yenza iThebhulethi yeWindows eguqulekayo esebenza njengeelaptops ezikhaphukhaphu.

iipilisi namhlanje

Ukusukela ngo-2010, akukhange kubekho mpumelelo ingako kubuchwephesha bethebhulethi. Ukusukela ekuqaleni kuka-2021, iApple, iMicrosoft kunye neGoogle ukuza kuthi ga ngoku abadlali abaphambili kwicandelo.

Namhlanje, uya kufumana izixhobo ezintle ezifana ne-Nexus, iGalaxy Tab, i-iPad Air, kunye ne-Amazon Fire. Ezi zixhobo zibonelela ngamakhulu ezigidi zeepikseli, ziqhuba uluhlu olubanzi lweewijethi, kwaye ngokulambisa ukusebenzisa i-stylus efana nekaKay. Mhlawumbi kunokuthiwa siyigqithile le nto uKay wayeyicinga. Ixesha liya kutyhila ukuba yeyiphi enye inkqubela esinokuyifumana kwitekhnoloji yethebhulethi kwixesha elizayo.
