Hello, I have been reading here for some time and have already found some very interesting discussions. I have a few new acquisitions of smartphone, laptop and/or tablet and I would like to take the opportunity to deal with security and privacy. My profile, requirements, ideas:

1 Profile:

large part of the year due to travelling not at my place of residence
occasionally longer stays abroad
staying mostly in hotels
experiences with Mac OS, iOS, Android, Linux, Windows

2 Which devices should be purchased:

Device 1: Smartphone (pixel with GOS)
Device 2: Laptop or Tablet (recommendations very welcome)
Device 3: laptop that remains in my house and where I can back up the other devices

3 Already bought:

Device 3: kindle
Device 4: AirPod Max

powerbank
data blocker
mobile phone contract with sufficient data for roaming so that I am not dependent on WLANs or local SIM cards

4 The following must be possible while travelling:

Signal/WhatsApp
Navigation
Surfing
Online banking
Music
Read
Access to passwords
Use of 2FA
Backup (device 1 <-> device 2)

5 ideas:

5-1 device 1: Pixel 9 with the following additional profiles:

Travel: Navigation, Booking.com, Apps for Airlines, Transport etc.
Bank: Online banking (TAN)
Communication: Email App, Signal, WhatsApp
Security: KeePass, 2FA App (2FA for account passwords which are stored in device 2)
Leisure: surfing, music, podcast

5-2 device 2: Here I am still looking for a suitable device and fluctuate between:

a second pixel
a pixel tablet
due to size: iPad Mini

Short: the device should ensure that in the case of a defect, loss etc. of pixel 9 all requirements (see 4.) can be met.

5.3 device 3

Stays at home and serves as a base to backup/restore the other devices.

What do you thing about the setup? Constructive criticism is very welcome. It would be very nice if you could send me recommendations for device 2 and 3 because I am soo lost there at the moment.

Merci!
