If he's already knee-deep in the Apple ecosystem, the iPad Air is the best choice. The iPad is the most popular tablet -- and one of the most expensive -- however, it's not for everyone.
Though it offers a multitude of apps and a sleek design, there is an abundance of tablets available that give the Apple slates a run for its money (and they're in this slideshow.)
It's not the latest 10-incher on the market, but the Nexus 10 still impressively holds its own against its competition -- trust me, it's a long list.
The Google Nexus 10 rocks a super-high resolution screen and comfortably lightweight design - especially for a 10-inch slate -- and since it's a Google branded tablet, it gets the latest OS upgrades as soon as they're available.
If your dad sometimes confuses you for tech support, then the Kindle Fire HDX tablets will provide you (and him) with some relief. The Amazon slates come with a Mayday button that almost instantaneously connects you with tech support, however, its simple OS tries to nip any problems in the bud with a user-friendly interface.
The 8.9-inch Kindle Fire HDX offers one of the most pixel-packed screens on a tablet and its ultra-lightweight and thin design give it a high-end feel. It's also pretty affordable to-boot.
Tell dad to put the paper down and pick up the Kindle Paperwhite. The e-reader is the best at replicating the easy-to-read pages of a book -- or newspaper -- without any of the cumbersome girth and weight.
If dad is a bookworm, or if you're just upgrading his old e-reader, the Kindle Paperwhite offers one of the best reading experiences out of any tablet, gadget, or doo-dad.
If you're on a budget, the Barnes and Noble SimpleTouch is an affordable choice. Its screen isn't as impressive as the Amazon Kindle Paperwhite, but it still gets the job -- or book -- done.
Though it's on the cheap side, it still offers a memory card expansion slot, Wi-Fi capabilities, and long battery life.
Does your father complain about how small gadgets are these days? Well the Samsung Galaxy Note Pro 12.2 should shut him up -- in the nicest way possible, of course.
The 12.2-inch behemoth won't replace his computer as a workstation, but it does offer an alternative way to get things done, with a large HD screen and handy stylus.
