Ranked in these QuestionsQuestion Ranking
Pro Great audio
The stereo speakers are tucked away along the front edge on either side of the screen. Sony is known to have good audio quality, and the Z4 Tablet doesn't disappoint. It gets pretty loud, and remains surprisingly good quality without going tinny at peak volume.
If you prefer to use headphones, the Z4 has high-res audio support, a very customizable equalizer, surround sound effects, and advanced noise canceling technology (if your headset has noise canceling capabilities.
Pro Good screen
The 2560x1600 resolution display is very crispy and has 299PPI which is very good for a tablet. It uses a more rectangular aspect ratio which is great for movies, but can make it a bit awkward to hold in portrait mode (which you'll need to do from time to time because some Android apps don't rotate to landscape.
You can submerge the Z4 tablet in 1.5m of water for up to half an hour (fresh water only). You don't have to worry about getting it wet, and it also stops dust in its tracks.
Pro Playstation Integration
If you own a PS4, you can stream games from the PS4 directly onto the Xperia Z4 Tablet. Sony calls this 'Remote Play'. Just download the PS4 Remote Play app and hook the tablet and PS4 together. It's highly suggested that you sync a controller to the tablet, otherwise you'll be stuck with a bunch of on-screen buttons.
You'll also need a fast network, otherwise the game streaming will be slow and unresponsive.
Con Very expensive
The Z4 Tablet is priced at more than it's worth. If you can find a sale of some sort, this is an easy recommendation...but at it's current price it's a tough sell.
Con Hard to find
In North America at least, Sony's mobile presence is almost non-existent. Most people want to try out tech before they spend nearly $600 on it, and that will be very hard to do with the Z4 Tablet.
