I'm guessing you mean new as in newer then the regular Switch? Because I don't think there's a new model, and turquoise is one of the original Lite color options.
Anyway, I have one and love it! I had a regular Switch for awhile but it broke- it stopped recognizing if the joy-cons were attached. I went to the internet for advice and everyone was like "GET A PRO CONTROLLER" and I'm like... I only play in handheld mode (I've never cared for home consoles, I mean I've bought them for exclusive games, but I have yet to play a game that I wouldn't prefer to play on a handheld console for convenience, and so I can watch TV WHILE I game). It was an enormously frustrating problem, and yet I never heard of anyone else having it, so I couldn't find any help for it. So, I was super pumped to get a Lite, and I love it! WAY easier to play in handheld mode, much lighter and more convenient. The battery life is nice, too.
The only real downside (besides the ability to switch, but some people seem to forget that plenty of players, like me, never use that option in the first place) is the durability, but almost every game system I've had I've had to replace at one point or another (I think I had a total of three 3DSes because they kept breaking, though I still have my original DS and it works fine, go figure), and if I have to replace it at some point, I will. It's cheaper and I would be able to afford a new one if I needed it, but I recognize I'm lucky in that regard.
I had one issue with joy-con drift once, but I ran a Q-tip under the stick and voila- all fixed! Now I do that regularly and I've had no other issues with it. Note that I DON'T run the Q-tip under the rubber part, just along the hole the stick sits in (IDK proper terms, lol)- I am careful not to get any fuzz stuck. Sometimes my characters don't quite move how I want them to, but there's a very good chance that's a "me" problem- I'm extremely clumsy and not very good at video games
I have that issue with most systems/electronics/objects so, yah, I think my fingers just aren't very nimble.
If they DID release a new, more durable model, without a risk of drift I'd be ON it, though! I'd definitely like if I didn't need to be quite so paranoid, lol.
