Smart Devices Trend: Why do i need a tablet if i have a laptop?

Tablets are smaller than laptops, but larger than smartphones with screens of between 7" to 11". Tablets are also better for viewing and use anywhere format. It's very easy to use right out of the box. Most tablets, have a capacitive touchscreen, these will work only with my finger, or a chunky capacitive stylus.

I love it, i can read e-books anywhere and hold up more than 1000 books. I can buy lowest e-book prices, over a million titles less than $9.99; over 600,000 titles less than $4.99; Million of titles in the public domain are available for free; Download and read first chapters for free before i decide to buy. I download books in under 60 seconds.

I can surf, email, note-taking, presentations, use social networking sites and chat in LINE, Whatsapp, WeChat and more.

When i teach, i use 7 inch Android tablet. The Android tablet can hold the presentation, and i can use it to control the slides in much the same way as i'd use my own laptop. My 7 inch Android tablet have mini-HDMI out. New projectors have two kinds of ports, a digital HDMI audiovisual port, or an analog VGA port -- or both. I connect tablet with the mini-HDMI cable, and then connect the standard HDMI cable to the digital projector.
