To make searching for the coolest products, ideas and gadgets on show a bit easier, we've collected our 10 favourites into the list below. But make sure to check out our deeper coverage on the show both here at HuffPost and over at our gadget-obsessed sister site Engadget. (Seriously, we saw those guys in the press room earlier - they haven't slept in weeks. Though they insist they have taken shower breaks.)
Yes, it's $4,500 and aimed initially at the business market. But Panasonic's 4K 20-inch Windows 8.1 tablet is pretty astounding in person.
Ricoh's new 'Theta' camera is a world first mass-market 360-degree cameraa. It's small enough to fit in your pocket, but takes remarkably good images using a twin-lens folded optical system. It syncs with your smartphone too, meaning images are easy to share and store. Find out more here.
Smartphones aside, Sony's big new idea at IFA was the QX series of screenless cameras. Essentially a lens you connect via Bluetooth to your phone, it makes any Android or iOS device capable of producing some really astoundingly good pictures - and it's half the price of a comparable camera.
3Doodler 3D-Printing Pen
This Kickstarter-funded gadget lets you make plastic sculptures without a printer or any fancy software. We saw a close demo, and loved it.
Samsung's Ridiculously Huge UHD tV
This 110-inch 4K TV over at Samsung's stand is so enormous and clear, you feel like you're falling into it. It's totally absurd - and no, you're never going to own one. But wow, will you want one.
It's hard to get that excited about an 8-inch tablet - unless it's the world's first 8-incher with a 1080P display. More pictures and info here.
Lenovo Yoga 2 Pro
We know - laptops aren't that exciting. But the Lenovo Yoga 2 Pro is something else. It has a 13.3-inch ultra high res display (3,200x1,800 pixels) which is just ridiculous - plus the same flexible hinge as the original, built-in voice control and it only costs around £1,000.
Panasonic's Tree Of 4K TVs
Panasonic's new 4K TV is cool enough on its own, since it's the world's first set with 60 FPS HDMI 2.0. But over at their stand, Pansonic built a literal tree of the displays and synchronised them to play similar, but linked and different videos of various scenes from nature. Neat.
In a show full of OLED TVs, how do you make yours stand out? Art. LG unveiled its new displays with the announcement of Gallery mode, which selects from a number of ultra-high res reproductions of famous paintings and displays them while the TV is in stand-by mode.
