Latest reviews and articles:
The Sony Xperia XZ Premium is a premium-spec version of the XZ, with a 4K HDR screen, a next-gen processor, enhanced camera, more memory and a bigger battery. It's a beauty for sure, and not over-priced, but may be too big for some users.
The Sony KD-55XE8596 is a mid-range 55-inch TV with 4K HDR support. The slim aluminium frame and silver slate stand with neat cable management are attractive, and the TV comes with the benefit of Android Smart TV too. Picture quality isn't a match for Sony's more expensive models, and we feel the price ought to be lower to reflect that.
The LG G6 is a premium metal-and-glass phone with a huge 5.7 inch HDR screen. Dual rear cameras, water resistance, Android 7 and a fingerprint sensor complete the package, but we're not sure why it's quite so expensive.
Sony's 55-inch XE9305B is a high-end LED TV that uses Sony's Slim Backlight Drive to generate impressive HDR images. Equipped with a 3-way audio system, it sounds as good as it looks. Factor in its slim good looks and Android Smart TV, and it's an all-round impressive TV. But the hefty price tag puts it out of range of most buyers, and there are smarter ways to spend your money.
The Samsung UE49MU6400 is a top mid-range 49-inch UHD TV with HDR support. Competitively-priced, with an upmarket stylish look, superb Smart TV functionality and connectivity, and excellent picture quality, it's a TV that's been very carefully tailored to provide everything you need for modern family viewing.
The Samsung 55MU8000 really brings 4K HDR content to life, with bright, vivid images and tons of detail. It's a stunningly beautiful centrepiece for your home too, with a sleek, high-end design. Samsung's Smart TV system is superb, and this is a top-rated premium 55-inch TV.
The EX750B is the top-end model in Panasonic's 2017 range of LED TVs and it's a UHD HDR model. The 50-inch screen is a very good size for family viewing, and this model is a solid all-rounder, with excellent picture quality, good Smart TV and connectivity, and a neat and flexible design.
The Galaxy Tab S3 is Samsung's best ever tablet, with a premium build, lightning-fast processor, and superb 10-inch HDR-ready screen. Its quad speakers and optional keyboard are also welcome. But the price is crazy, and it's the first Android tablet we've seen that costs even more than the equivalent iPad.
The Sony 55XE9005 might just be the best TV you can buy for the price in 2017. The direct backlit screen with local dimming delivers outstanding picture quality, whether showing HDR or normal video content. And with a smart, premium design, the benefits of Android TV, and a decent audio system, it's got the lot.
