I’ve been using a Cintiq 12wx ever since it came out a few years ago. It’s amazing because it’s so much more efficient compared to using a regular tablet. It’s also very durable - it’s been with me during all those grueling times I never switched off my computer while rushing doujinshi/prints, it hasn’t had any overheating problems (actually it doesn’t even feel all that warm). The only downside to it is that it’s definitely not portable, and the cables take so much space. Also, in all these years, the cables don’t seem to take well to HK’s humidity, and are showing signs of rust. But overall, this toy paid well for itself. I can never ever go back to using a regular tablet.
I got the Cintiq Companion about 2-3 weeks ago. It’s a tablet and computer in one, without any cables. Even the battery is tiny and lightweight. It’s very portable. Sometimes, when I’m too lazy to get out of bed, I’ll just use this instead lol.
I’m still very much attached to my 12wx though, because it’s been with me for so many years and there’s a lot of good memories associated with it. It’s the very reason why I started participating at doujinshi events in the first place. Also, it took a long time for me to save up for it back then because I was poor as shit and I worked very very hard for it.
