the computer you need in your hands, i have a second-hand Dell USB-C ultrasharp monitor and it works like a charm with my phone. Add my logitech wireless combo and USB-HIFI stereo DAC - i have the perfect setup for SaaS based work
Samsung DEX definitely a great feature on both tablet and mobile device. Especially on tablet i believe.
Samsung tab S9 coming up soon. I heard there will be IP67 water resistance. Lol.
