The Roku 3 is our current top pick in the Internet media box category. It's the best overall choice for online streaming, with literally hundreds of channels -- pretty much everything except iTunes and YouTube. Just make sure you help Dad setup his Netflix, Hulu Plus, HBO Go, Amazon Instant, and/or Vudu account first.
Dad probably isn't savvy to the whole world of online backup, but he gets drag and drop copying. That's why a Seagate Backup Plus USB drive with a whopping 1TB of storage (that's 1,000 GB for just less than $100) is a great gift.
Logitech's most affordable Harmony universal remote is also one of the most recommendable. Program it via the Web on your Mac or Windows PC, and control up to 5 devices at once. Perfect for dads who are couch potatoes -- or control freaks.
Music lovers will appreciate these "I can't believe they cost less than $60" Dayton Audio speakers. But they're not self-powered, so make sure Dad also has an amplifier (or just toss in the $25 Lepai LP-2020A+ for good measure.)
Yes, tablets and smartphones can double as e-book readers. But the $69 Amazon Kindle has a long-lasting battery and a paperlike screen that avid readers will appreciate. And unlike more versatile devices, there won't be any calls, e-mails, or texts to distract the reader, either. (You'll need to pay $119 if you want to step up the self-illuminated, touch-screen Paperwhite version.)
If Dad prefers to hang out at the local Barnes & Noble, the basic Nook Simple Touch may be a better choice than the Kindle. And unlike the slightly cheaper Kindle, the $79 Nook has a touch-screen -- and no ads. (The GlowLight version costs $40 more.)
The Jawbone Jambox gets all the press, but the JBL Flip is our favorite Bluetooth speaker for under $100. It's portable, rechargeable, has speakerphone capability, sounds great for its size, and works as a wireless speaker with virtually any smartphone or tablet. The perfect way to introduce Dad to the world of wireless audio.
