  • Huawei Matepad 11 - Premierowa Recenzja Tabletu Z Harmonyos
    Huawei MatePad 11 - premierowa recenzja tabletu z HarmonyOS Wpisany przez Maksym Słomski Środa, 04 Sierpień 2021 11:00 Tablet z HarmonyOS. Huawei konsekwentnie rozwija swój ekosystem produktów wykorzystujących oprogramowanie HarmonyOS. Nie ukrywam, że moje zainteresowanie tym oprogramowaniem rozbudził pracujący pod jego kontrolą zegarek Huawei Watch 3 Pro Elite . Nazwałem go w swojej recenzji smartwatchem niemal doskonałym i zdanie to podtrzymuję. Przyznam, że z nieco mniejszym entuzjazmem, choć ze sporą dozą ciekawości podszedłem do recenzji tabletu Huawei MatePad 11. Entuzjazm nie był ekstremalnie duży, bo wydawało mi się, że wszystkie tablety poza iPadem Pro umrą w końcu śmiercią naturalną. Szczerze: nigdy nie byłem wielkim miłośnikiem tabletów. Z ciekawością, gdyż byłem ciekaw, jak HarmonyOS spisuje się na sprzęcie z 11-calowym ekranem. Po dwóch tygodniach spędzonych z Huawei MatePad 11 stwierdzam, że to jeden z najciekawszych tabletów, jakie miałem w dłoniach, choć do ideału trochę mu brakuje. Huawei MatePad 11 - specyfikacja Huawei MatePad 11 otrzymałem w minimalistycznym, kompaktowym, schludnym i ładnie zadrukowanym opakowaniu. Wewnątrz znalazłem ładowarkę o mocy 22,5 W, przewód USB-A - USB-C oraz przejściówkę z USB-C do jack 3.5 mm, która zdradza pierwszy drobny mankament urządzenia: nie wyposażono go w złącze audio. Swoją drogą, czy niemal wszyscy nie przerzucili się już na słuchawki bezprzewodowe? Dajcie znać w sekcji komentarzy. Wraz z tabletem nadesłano mi komplet akcesoriów, które znacząco zwiększają spektrum zastosowań urządzenia. I tak, równolegle sprawdzałem możliwości Huawei Smart Magnetic Keyboard, czyli etui magnetycznego z klawiaturą, rysika Huawei M-Pencil oraz myszki Huawei Bluetooth Mouse. Dysponując powyższymi miałem czasem wrażenie, że korzystam z laptopa z 1 / 9 Huawei MatePad 11 - premierowa recenzja tabletu z HarmonyOS Wpisany przez Maksym Słomski Środa, 04 Sierpień 2021 11:00 ekranem dotykowym.

  • 1 Data Appendix B
    Data Appendix B: Articles used for the coding process In this document, I have bundled the articles used as input for the coding process in Atlas.Ti. I have bundled interviews with Huawei CEOs and rotating chairmen, articles from U.S. based technology websites and articles from Chinese based technology websites. I started the data collection process by looking up trustworthy and popular U.S. based technology websites using Detailed.com and Get.Tech. Following the most popular website mentioned on Detailed.com – TheVerge – I started browsing to this website and I subsequently entered the key search terms as mentioned in the Thesis document. I scanned articles that either discussed Huawei’s platform expulsion from the Android platform or Huawei’s competitive response following the ban. When articles referred to other websites, I used mediabiasfactcheck.com as a tool to judge the objectivity of reporting of the respective websites. For example, this article of TheVerge contains the original source from Reuters, so I used mediabiasfactcheck.com to ensure that the original Reuters source was of high quality. Using this website, I found that Reuters scored very high on “Factual Reporting” and is considered one of the “least biased” websites. However, not all websites listed below could be found on mediabiasfactcheck.com, so I aimed to triangulate the data of sources by using multiple data sources that covered the same topic but described it from a different perspective. For example, most Chinese sources could not be traced by mediabiasfactcheck.com and in general, it is very hard to find if Chinese sources are trustworthy and of high quality.
