One of the greatest
feature of “certain” Android devices is the ability to connect
to USB devices via OTG (On-the-Go). Your phone or tablet is no longer
the device but the host. You have the ability to connect USB drives
as mass storage or the ability to plug in a mouse or keyboard.
For me, the coolest
thing is the ability to use a phone or tablet as a
vt100/hyperterminal/minicom terminal. For years, in data centers, I
used a IBM Workpad Z50 (Windows CE) or a Windows laptop running
hyperterm to connect to switches, routers, firewalls, UPS and the
likes.
For less than 2ドル (Amazon Link
)
you can get an OTG
cable to work with your Android device.
I was able to
successfully connect a Galaxy Nexus and a Galaxy Tab 2 7” (using a
different 30-pin to OTG cable) to various switches and firewalls.
That was a geek epiphany moment
