Get ready to hear the words "liquid surface" thrown around a whole lot.
But not just any glass. HTC calls it Liquid Surface, but what the heck does that mean? It it just marketing gumph, or is there something to it?
And more importantly, is it enough to make you want one? Here's everything you need to know.
Haven't I heard this before?
If you've been paying attention to HTC's other phones, then yeah - there's a good chance that Liquid Surface won't sound entirely unfamiliar.
Those handsets didn't exactly set the phone world alight, though, and there's a good chance they could have flown under your radar.
That won't happen with the HTC U11, though: it's HTC's flagship, set to take on the might of Samsung's Galaxy S8, the LG G6, Huawei P10 and Sony's Xperia XZ Premium. Oh, and the small matter of the iPhone.
So you'd better believe it's a big deal.
So what exactly is it?
Liquid Surface is, essentially, a colour treatment that gives regular ol' glass a more style-centric overhaul.
Different colours are added to layers of glass, with subtle variations (in the case of the Sapphire Blue, Brilliant Black and Ice White versions) or more contrasting colours (like the Amazing Silver and Solar Red handsets) in each layer. When you hold the phone up to the light, it'll reflect and show the different colours shining through.
The Brilliant Black phone has hints of green, Ice White has a pearl-like texture with reds and pinks appearing at certain angles, and the Sapphire Blue has several different shades, rather than a single flat colour. Compared to the single colour glass seen on a Galaxy S8, HTC's phones look a whole lot snazzier.
And that's before you pick up the Amazing Silver version, which has blues and purple undertones, or the incredible Solar Red phone, which looks like crimson from the front, but somehow turns into a dazzling gold at an angle.
The glass isn't flat, either. It's moulded at the sides and edges, so it sits more comfortably in your hand. This isn't unique - just take a look at the 2.5D glass on the iPhone 7 - but HTC has gone further to give the impression of liquid metal, or the natual surface tension of a water droplet.
