📝 Discussion Summary (Click to expand)

1. Logitech K‑series keyboards – Many users love the compact K380/K480 for travel but report mixed experiences.

“Logitech k480? Oh my god and it even has round keys!” — gblargg
“The slot is handy for iPad and iPhone simultaneously.” — wisher
“I also like my K480… they hold in securely enough to carry it around the house.” — gblargg

2. Preference for ultra‑portable, sometimes foldable, keyboards – Travelers seek tiny Bluetooth keyboards that fit in a bag or pocket, even if they sacrifice key feel.

“Look what they have at Walmart now :) … it’s heavily weighted so it will support the devices in the slot without tipping over.” — fuzzfactor
“I got a pocket‑sized Bluetooth keyboard (195 × 85 × 15 mm) with a flap – NOT a foldable keyboard, though it does have a cover flap and a kickstand.” — JoshTriplett

3. Durability & ergonomics of other input devices – Trackballs and mice often fail after a year; users resort to DIY repairs or accept wear.

“I have M570 trackball… the switch fails in one year and starts double‑clicking like crazy.” — albert_e
“My MX Master 3s/4 is my perfect mouse… the rubber coating gradually disintegrates and accumulates dirt.” — jordand

4. Using smartphones as desktop‑class workstations – Desire to dock phones with keyboards, monitors, and run full‑featured tools like Termux or DeX.

“If you get an Android you can use Termux and do literally anything… run docker, compile, etc.” — tnelsond4
“I can plug in the same USB‑C dock I use for my Mac and everything just works on the Android phone.” — mattlondon
