My first ukulele was functional but pretty plain and it was my goal that when I got a better uke that it would have some inlay that I like. I was able to find one made from quality materials that also happens glossy and has a lot of inlay. Regardless, I enjoy the sound and I enjoy the feel of the instrument in my hands.
What's more, though, is that I love to open up the case and look down while thinking, "I get to play this beautiful thing." I don't play the ukulele to impress anybody--I play for my own pleasure. Part of that pleasure is visual so I have no regrets. I'm sure there are people on this forum who would think my ukulele is gaudy but, lucky for them, I didn't pick out or pay for an uke for their benefit. I can appreciate the beauty of a simple but well-crafted instrument, too, and I respect a player's skill more than the look of his or her instrument but, thankfully, there's a wondrous variety for everyone to choose from and the internet puts them all at our fingertips.
My little tenor brings me joy on many levels (including being eye-candy) and that's all I want from it.
