As well as all of those apps, VIERA Connect is also one of the few online platforms to include an online shopping dimension.
Sign-up with a bank card and you can order the latest accessories (a Skype headset with cost you £120.25 for the TY-CC10W model, or £88.72 for the TY-CC20W), while Panasonic's 3D glasses are available in several flavours, costing from £16.13 to £80.65 at the time of writing.
There are also a few games, though months after launch we're still only talking Uno, Asphalt 5 and Let's Golf, which can each be downloaded to VIERA Connect for £3.44.
Other apps of note in the Marketplace include Twitter, Facebook and Social Media TV, the latter of which makes use of the set's dual-core processor to put your Twitter or Facebook feed directly beside the live TV feed; chattering away has never been easier – and this idea could really catch-on during the 2012 Olympics.
So too the new multi-screen BBC Sport app, itself a thing of wonder; who needs the iPlayer? Not sports fans, that's for sure, though seeing as the BBC has limited and ever-decreasing broadcast rights to sports, it may not be much use beyond London 2012.
Two pairs of Panasonic's mid-range TY-ER3D4M Active Shutter 3D glasses (which you can buy on the VIERA Connect Marketplace/accessories for £64.52) are included in the box.
The 'M' stands for medium-sized; 'S'-sized versions can be bought for the same price. The specs themselves are chunkier than those supplied with Samsung TVs, but are designed to keep light out more effectively.
As well as Active Shutter 3D, the TX-L47WT50 includes both Freeview HD and Freesat HD tuners, a 1,600Hz system (though don't be fooled – it's a not-to-be-underestimated 400Hz brain with backlight scanning), Smart VEIRA Engine Pro (which includes Intelligent Frame Creation to banish blur, and a 24p Smooth Film to get rid of Blu-ray judder), 2D-3D conversion, Wi-Fi to aid VIERA Connect, and Bluetooth for fuelling those accessories.
The final innovation is a Touch Pad controller, a handheld device with a touch-sensitive pad for operating the TV via Bluetooth, though a regular remote is also provided.
Ins and outs are as extensive as they get, with four HDMI inputs on the side, three USB slots (one of which can record Freeview programmes to an HDD, or pause live TV to a USB stick), and an SD card slot.
Back there you'll also find adaptors for component video and Scart, a D-sub 15-pin VGA port for hooking up a PC or laptop, an optical digital audio output, and a wired Ethernet LAN slot.
