As much as I'd like to favor foss and federated messenger apps, telegram isn't as much garbage as whatsapp:
1.The client is somewhat open source and have forks like Forkgram, Materialgram and unoffical clients like Telegrand.2. Telegram isn't E2EE by default but at least it doesn't lie about it and have E2EE secret chat when nessesary, that means crucial chats stay on your device and the rest stay on their database recoverable and syncable across devices.(Yes, whatsapp supposedly is E2EE but we can't know for sure, it's closed-source.)3. You can use telegram as a cloud service with only 2GB per file limit, unlike whatsapp.(There's even a third-party app that utilise this as a cloud gallery.)4. Even tho telegram has ads in large channels, telegram isn't funded by a greedy big-corp and it doesn't datamine you, ads are based on the channel's topic.
Yes, in terms of privacy, telegram isn't the best option, Signal, Session, XMPP, Matrix, or SimpleX have better privacy features, less linkability and E2EE by default but telegram is very mainstream and got more publicity, making it the whatsapp alternative it advertises itself as-is.Publicity doesn't make a better messenger app, but for what it tries to do, it's adoptable for simple users, doubles as cloud storage and is more secure than the garbage being whatsapp.
Immigrating users to different apps is a headache on it's own, but if they know of telegram and it's not privacy invasive, that's not bad.

IDK if this is a usable design...it looks like a large tablet convertable to a labtop, not a foldable laptop of it's own.
Also, is it X86 or Arm CPU?
