I love my 2014 WDTV and im looking forward to the 2015 version (hopefully there will be one), but here are my main suggestions.
A faster processor. Throw a quad-core chip in there! Hopefully one that supports 4K video. When I click a button on the remote, I don’t want to be waiting a second or two for it to register on-screen. It needs to be instantaneous. This is important, it’s 2015. I would happily pay a premium for it to have a Tegra K1 inside.
The remote, please add volume controls to it. A headphone jack would be nice too but that isnt critical, volume controls are critical.
More USB ports on the back, this would be great for connecting multiple drives.
The User Interface needs some work, it’s currently very unintuitive to do basic tasks. I still cant figure out how to copy a video file from a USB flash drive connected to the front into a USB HDD connected on the back. This is useful if we want to quickly get files on the WDTV without having to disconnect the main drive. Also, please add a ‘safely remove’ function to eject the drive without having to power off first.
The UI design is OK, but it seems like it’s trying too hard to impress. Something minimal and clean would do just fine, in addition to using less resources. Think Windows 8-style design, it would work and look great on a TV.
Those are my main suggestions. I’m really looking forward a new WD TV. And honestly, if it only had the first two suggestions it would be a great improvement. Please don’t disappoint with the next version.
