No sleep, barely passable Spanish, and a bag full of spare batteries, chargers and Red Bull. Mobile World Congress is here.
The Barcelona-based event is rapidly becoming one of the most important events in the tech calendar. It's been a launchpad for generations of flagship smartphones from the likes of Sony, HTC, Samsung and more, and it now covers the most exciting emerging trends in consumer technology, including wearables and the Internet of Things.
We've got front row seats right here in the sun, but there's no time to enjoy the sights. There's far too many pieces of shiny tech to wrap our hands around.
Here's a roundup of all the best news so far:
LG - Spec-tacular G Pro 2 meets the shrunken G2
There's no G3 here in Spain however. It's likely that the G3 will instead launch just before IFA in September, which is when the G2 first took to the stage last year.
LG also introduced the already-announced G Pro 2, which we also got to play with. It's got a 5.9in full HD screen, quad-core Snapdragon 800 processor, 3GB of RAM innards, and a 13MP camera with OIS+, 4K video and 120fps full HD slow motion capture.
It also features a number of useful software tweaks including the ability to unlock itself with a specific screen tap pattern, which LG calls Knock Code. You can also shrink the screen down for easy one-handed use.

Sony - Xperia Z2 struts its stuff
Mobile World Congress ushers in the arrival of the Sony's latest flagship, the Xperia Z2.
It's got a slightly larger 5.2in full HD screen (not QHD as previously thought), though it packs in Sony's Colour LED tech which provides a wider range of colours for more accuracy.
Sony's tried and tested Xperia design returns with a slightly slimmer waterproof body. It's also got digital noise cancellation for clearer calls.
It's got a boost in the power department too, with a quad-core 2.3GHz Snapdragon 801 processor and 3GB of RAM which should handle Android 4.4 KitKat with ease.
A 20.7MP camera finishes off the spec list, with 4K UHD video recording, image stabilisation, slow-motion video capture and integrated AR and Vine functionality.

Sony will also has a tasty treat for tablet fans in the form of the Xperia Z2 Tablet - the world's thinnest and lightest waterproof tablet, measuring in at just 6.4mm thin.
Its 10.1in screen keeps the full HD resolution, but, like the Xperia Z2, features Sony's Colour LED tech.
The speakers have been moved to the front for clearer audio, and it packs in the same Snapdragon 801 processors and 3GB of RAM as the Z2.

Sony also revealed a treat for fans of wearable gadgets too, in the form of the SmartBand SWR10 fitness band, which tracks everything from your fitness stats to what music you were listening to and when.
Samsung - Galaxy S5 (aka thunder-thief)
Day one's biggest reveal was probably the Samsung Galaxy S5, the company's new flagship phone. It's a powerful quad-core mobile with a number of intriguing features and what seems like less of the gimmickry that has loaded up previous Galaxy S phones. Samsung was keen to hammer the "we're listening to what consumers really want" drum again and again, and that surfaced in an improved camera, better build quality, built-in fitness features and a fingerprint scanner.

Samsung has also taken the wraps off not one but two new Galaxy Gear smartwatches; the Galaxy Gear 2 and Galaxy Gear 2 Neo, both powered by Samsung's own Tizen OS rather than Android. Not to mention the Galaxy Gear Fit, its own take on the fitness band and blessed with a curved glass screen.

HTC - wristy business
Sadly the HTC One Plus (or M8) won't be surprising us in Barcelona with its rumoured 5in 1080p display, Snapdragon 800 processor and Android 4.4 KitKat with Sense 6.0.
Instead, it'll get its own special launch event in both London and New York on 25 March.
HTC did however unveil the Desire 816 phablet. It's got a 5.5in 720p display, quad-core Snapdragon 400 innards, 1.5GB of RAM and a 13MP snapper.
It also unveiled a smaller, lesser specced 4.7in Desire 610.

Pre-MWC rumours pointed to a HTC smartwatch based on the Qualcomm Toq. Its Mirasol colour E-Ink display should offer much better battery performance than the Samsung Galaxy Gear and Sony Smartwatch 2, while its colours better the Pebble's greyscale display.
HTC is also reportedly working on a smart band for music playback and fitness tracking, along with a Google Now-powered smartwatch.
Sadly, we didn't get a chance to see any of these wearables at MWC, as HTC reportedly showed them off to mobile carriers behind closed doors. Boo.
Nokia – Hello Android
Nokia has revealed three new Android (yes, Android) devices, one of which is the previously leaked Nokia X (Normandy).
The X, X+ and XL all run a heavily modified version of Android. Like the Kindle Fire HDX series of tablets, there's no native Google Play Store.
Instead, users will have access to Nokia's own App Store. There will also be baked-in Microsoft Services including Onedrive, Outlook and Skype.
The X features a 4in screen with a 3MP camera and dual SIM slot, and it'll retail at a budget friendly €89.
The €99 X+ will feature more memory and storage, as well as a microSD slot, while the €109 XL has a 5in screen and 5MP camera.
Detailed specs have yet to be revealed, but we'll keep you updated.
Fujitsu - you won't believe your fingers
Fujitsu's proof-of-concept tablet has absolutely blown our fingers away.
It uses ultrasonic inducers on the screen, causing it to vibrate it at different frequencies. A picture of a crocodile feels rough to the touch while plucking the strings of an instrument cause actual vibrations. Absolutely magical.
Lenovo - it's Yoga time
Lenovo's original Yoga 10 tablet as great. We loved its unique design and built, which featured a built-in kickstand and super long battery life. It was however let down by an awful low-res screen, and weak insides.
Luckily for us, Lenovo has revealed an update - the Yoga 10 HD+, which addressed both problems with a full HD display and quad-core power.
The Eye Tribe - forget fingers
The Eye Tribe showed off its eye-tracking sensor which we took for a spin on the MWC show floor, and we left its stand suitably impressed. It's looking for existing manufacturers to bake in the simple, cheap hardware, so hopefully it won't be too long before we're flinging angry birds without having to lift a finger.
Ibis - design rules
Ibis' smartwatch concept demonstrates how wearables can actually look good, while serving up useful information at the same time.
More jewellery than smartwatch, we're looking forward to seeing what other designs the company will reveal. Our wrists could do with something a tad manlier, after all.
