The other day, I had a problem with Sublime Text not playing nicely with whatever version of GIO/GVFS I had on the system to open a file over SFTP. I went back to Vim and the netrw plugin because I didn't like the idea of paying $20 for a Sublime Text plugin for something it should be doing natively.
Cue 2 hours of cursing at the Vim setup - there were no errors, I just didn't get any remote directory listings in netrw. I also didn't have any colours for some reason, and #vim on Freenode couldn't help.
Sometimes, the older tools are just as frustrating.
In any case, I feel like a lot of the latest-and-greatest fetish in tech is driven by people who don't "just fix it", and are therefore constantly on the lookout for the next big thing that will solve all your problems and give you a chocolate-covered puppy. Most of the time that I've decided to use a "simple, new" tool, I've quickly found out that the reason the tool is simple is because I Have To Fix It, and that once I've Fixed It, I have a tool that was as complicated as the "complicated, old" tool, but totally unsupported.
