Ngo-1972, u-Alan Kay, usosayensi wamakhompyutha waseMelika, waqhamuka nomqondo wethebhulethi (okuthiwa i-Dynabook), awuchaza kabanzi emibhalweni yakhe eyanyatheliswa kamuva. U-Kay ucabange idivayisi yomuntu siqu yekhompyutha yezingane ezosebenza cishe njenge-PC.

I-Dynabook yayinepeni elilula futhi inomzimba omncane onokubonisa okungenani amaphikseli ayisigidi. Onjiniyela abahlukahlukene bamakhompyutha baphakamise izingcezu zehadiwe ezingase zisebenze ukwenza lo mbono ube impumelelo. Nokho, isikhathi sasingakafiki, njengoba amalaptop ayengakasungulwa.

1989: Inkathi Yezitini

Ikhompuyutha yokuqala yethebhulethi eyakhishwa okokuqala emakethe ngo-1989 ngaphansi kwegama elithi GRidPad, igama eliqanjwe Kuhlelo Lwegridi. Kodwa-ke, ngaphambi kwalokho, bekunamathebulethi ehluzo axhumeke kuzindawo zokusebenza zekhompyutha. Lawa mathebulethi ezithombe avunyelwe ukudala izixhumanisi ezihlukile zabasebenzisi, njengokugqwayiza, ukudweba kanye nemifanekiso. Basebenza njengegundane lamanje.

I-GRidPad yayingekho eduze nalokho okwachazwa yiDynabook. Zazinkulu, zinesisindo esingamakhilogremu amathathu, futhi izikrini zazikude nebhentshimakhi yephikseli eyizigidi zika-Kay. Amadivayisi nawo awazange aboniswe nge-grayscale.

1991: ukukhuphuka kwePDA

Ekuqaleni kwawo-90, abasizi bedijithali bomuntu siqu (ama-PDA) bafika emakethe ngokudumala. Ngokungafani ne-GRidPad, lawa madivayisi ekhompuyutha abenesivinini esanele sokucubungula, imidwebo efanelekile, futhi akwazi ukugcina iphothifoliyo evulekile yezinhlelo zokusebenza. Izinkampani ezifana neNokia, i-Handspring, i-Apple, ne-Palm zaba nentshisekelo kuma-PDA, ziwabiza ngobuchwepheshe be-pen computing.

Ngokungafani nama-GRidPads asebenzisa i-MS-DOS, amadivaysi ekhompyutha epeni asebenzisa i-IBM's PenPoint OS nezinye izinhlelo zokusebenza ezifana ne-Apple Newton Messenger.

1994: Kukhululwa ithebhulethi yokuqala yeqiniso

Ngasekupheleni kweminyaka yama-90s umbono wenoveli wesithombe sikaKay sethebhulethi wawusuphelile. Ngo-1994, uFujitsu wakhipha ithebhulethi ye-Stylistic 500 eyayinikwa amandla yi-Intel processor. Le thebhulethi ifike neWindows 95, ephinde yavela enguqulweni yayo ethuthukisiwe, iStylistic 1000.

Nokho, ngo-2002, konke kwashintsha lapho iMicrosoft, eholwa nguBill Gates, yethula i-Windows XP Tablet. Lo mshini wawunikwe amandla ubuchwepheshe be-Comdex futhi wawuzoba yisambulo sekusasa. Ngeshwa, i-Windows XP Tablet yehlulekile ukuphila ngokuvumelana ne-hype yayo njengoba i-Microsoft ingakwazi ukuhlanganisa isistimu yokusebenza ye-Windows esekelwe kukhibhodi ibe idivayisi ekwazi ukuthinta i-100%.

2010: Idili Langempela

Kwaze kwafika ngo-2010 lapho inkampani kaSteve Job, i-Apple, yethula i-iPad, ithebhulethi enikeza konke abasebenzisi ababefuna ukukubona ku-Kay's Dynabook. Le divayisi entsha isebenze ku-iOS, isistimu yokusebenza evumela izici zokwenza ngendlela oyifisayo kalula, isikrini sokuthinta esinembile kanye nokusetshenziswa kokuthinta.

Ezinye izinkampani eziningi zilandele ezinyathelweni ze-Apple, zikhulula imiklamo ecatshangelwe kabusha ye-iPad, okuholela ekugcwalisweni kwemakethe. Kamuva, iMicrosoft yalungisa amaphutha ayo angaphambili futhi yakha i-Windows Tablet esebenziseka kalula, eguqulekayo eyayisebenza njengamakhompyutha aphathekayo angasindi.

amaphilisi namuhla

Kusukela ngo-2010, akubanga khona impumelelo eminingi kubuchwepheshe bethebhulethi. Kusukela ekuqaleni kuka-2021, i-Apple, iMicrosoft ne-Google kuze kube manje bangabadlali abakhulu kulo mkhakha.

Namuhla, uzothola amadivayisi amahle njenge-Nexus, i-Galaxy Tab, i-iPad Air, ne-Amazon Fire. Lawa madivayisi anikeza amakhulu ezigidi zamaphikseli, asebenzisa amawijethi anhlobonhlobo, futhi awasebenzisi nhlobo ukuloba okufana noka-Kay. Mhlawumbe kungashiwo ukuthi sikwedlule lokho uKay ayekucabanga. Isikhathi sizodalula ukuthi ikuphi okunye ukuthuthuka esingase sikuthole kubuchwepheshe bethebhulethi esikhathini esizayo.
