Another convert here. Grew up with woodwinds. Switched to guitar about 13 years ago and have played them on and off for that time. Got serious about uke last August, and now the serious has become the obsession. I am quite certain if I had met the ukulele prior to the guitar, there probably wouldn't have been guitars in my life. I do love all stringed instruments, but I have made more progress on the uke; and been more satisfied with it in the scant months I have played, than all the years I have worked with guitar.
Although guitar is fab, I have struggled with it so; and have to work so hard to achieve what I consider--mediocrity. I have accepted I seem to be on a perpetual guitar plateau. I have no natural musical gifts. All my progress is hard won through practice and straight up work and I still feel like such a beginner. I so envy/admire those who can pick up an instrument and play by ear, and play well quickly--but that will never be me!! However, the uke has revived my hope that maybe, just maybe if I keep at it that...SOMEDAY I can be really good. The tickle is there in the back of my brain. I never really got that with the guitar.
In the meantime, I usually do not go a single day without playing both instruments; but the uke gets most of the love. Plus, holding a guitar is now like cuddling a baby water buffalo in comparison to the uke. The uke is also so much easier on my left wrist tendonitis that keeps rearing its ugly head. And, so important, the uke is beautiful because it is such a constant companion, the size guarantees it!!
