haha I know what you're talking about, I love warm destinations as well
Cabarete definitely has been one of my favorite spots in the past, especially during the winter time. It gets pretty crowded during New Year's and Christmas but after that it's fine again. Wind chances in winter are like 50-60% so it won't be windy every day but if you stay there for a longer period it will be fine you will still get enough windy days. I also wrote a spot guide for Cabarete here: http://wakeupstoked.com/kitesurf-cabare ... -republic/
Another amazing spot (but the season ends End of January/beginning of February) is Jericoacoara in Brazil. It has been a small hippie village, all built on sand, and has been growing more and more popular in the last years. You can literally kite in boardshorts! Every day you can take a buggy to a different spot or choose to do a downwinder. Also wrote a super detailed guide with downwind options about Jeri here: http://wakeupstoked.com/kitesurf-jericoacoara-brazil/
Since this year Jeri has glassfiber connection in some pousadas, but make sure to really choose one according to internet connection (there is a facebook group called Jericoacoara Digital Nomads https://www.facebook.com/groups/981128428593660/
, they should know about that).
I haven't been there yet but Mui Ne in Vietnam is also supposed to be pretty good, warm water and lots of Digital Nomads go there now so the internet connection should be pretty decent.
In general, if you're interested in kitesurfing and working remotely or having a good internet connection, you could join the facebook group Kitesurf Digital Nomads: https://www.facebook.com/groups/1651245441806236/
