Some have touch, some don't, some have detachable "tablet" screens, most don't... NO consistency. When was the last time you saw someone sitting in front of you typing on a laptop, and then they suddenly pull the screen off because they want it as a tablet? My experience count of this: ZERO, not ONCE have I seen this or had ANYONE ask me "what is the best laptop I can buy where I can rip the screen off and turn it into a tablet?" - it just DOESN'T HAPPEN. EVER.
If ripping off your screen was such a good idea... if touching your laptop screen, VERTICALLY, was such a good idea, why do SO FEW people want it or use it? People want an iPad and a MacBook, or an iPad and a laptop - not this quarter-baked hybrid, halfway house compromised experience - iPad is THE default, de-facto go-to tablet, it's ubiquity and notoriety are legendary, unparalleled - NEVER ONCE has anyone asked me "where can I buy a Windows 10 tablet?" - N_E_V_E_R, but MANY people ask me "do you know anyone selling an iPad?"
