It seems there is enough demand for on-the-move HD video that Sony feels the need to release a portable Blu-ray player of its own, joining other manufacturers such as Panasonic. The BDP-SX1 was announced earlier this year and has recently gone on sale in the UK and around the world. So what do you get for your money?
Like other similar products, the SX1 looks like a chunky laptop, but in place of a keyboard there's a disc tray. The screen measures 10.1" and has a 1024 x 600 pixel resolution, which as most will understand is considerably less than true HD - although you'd hardly notice any difference on a screen this size anyway.
In addition to playing discs, a USB socket lets you play digital media (including pictures and music) from a memory stick, however there's no Wi-Fi to enable streaming video while out and about.
The SX1 has a remote control and an HDMI-out, so it could be used as a regular Blu-ray player in your home and it supports the usual DTS Master Audio and Dolby TrueHD audio feeds, plus it happily plays DVDs and CDs too. It's not 3D compatible though.
Sony quote a battery life of 5 hours and the player is driven by Sony's excellent XMB menu system, making it very easy to use.
The Sony SX1 is available through Sony for the full retail price of £299, but if you shop around it's possible to reduce this by £50-£70. The only thing is, a small amount more could net you a Blu-ray player in a laptop, a far more versatile product than the SX1.
