One of the hardest parts of building Responsive WordPress themes is maintaining responsive integrity after the site goes live. User Admins can have limited coding abilities which can prevent them from maintaining responsiveness in themes.
WP Mobile Detect aims to make it extremely easy for anyone to wrap content in the editor with shortcodes which will hide content based on visitor device at the server level.
No longer do we need to rely on display:none; or other techniques to hide content for mobile devices. Instead we can replace content with alternatives. When a full-size infographic in your post is unknowingly displayed on a visitors phone we can consider that an Non-user initiated download. In other words that visitor had no idea what they were getting into and you possibly just choked their bandwidth.
WP Mobile detect gives you the ability to wrap that infographic in a [notdevice][/notdevice] shortcode so at the server level WordPress will decide to show that content only if the user is NOT on a phone or tablet. Alternatively you can wrap a link and corresponding text to that info graphic in a [device][/device] shortcode as a way for the visitor to consume that content if they so choose.

Mobile detect plugin uses the open source <a href="http://mobiledetect.net/" rel="nofollow ugc">MobileDetect PHP library</a> to fine-tune the built-in WordPress function <code>wp_is_mobile()</code> in such a way that tablets are excluded from being detected as mobile!
If you don’t understand the above one-liner, here is some explanation…
If we serve different (cached) content for mobiles and desktops, iPads (and other tablets) are usually served with mobile version of the site. That means, iPad users see only the mobile version of the site. If you are in doubt, check your site now! There is nothing wrong with your iPad (or any other tablet). It is due to how WordPress treats iPads and other tablets. Currently, in WordPress, iPads (and other tablets) are considered as mobile! One day (in the future), tablets may be considered as desktops by WordPress internals. Until then, by using / activating this plugin, tablets are served with desktop version of the site.
If your site doesn’t serve different content for mobiles and desktops, please ignore this plugin. This plugin does nothing in that case.
