I wouldn't agree with this (since we have applets in production where I work). However I would say that applets are a minor feature and that you shouldn't learn them until (a) you need them and (b) you already know Java well enough so that you only need half a day to get up to speed on them.
We give our customers these little palm-sized barcode scanners. They go around their store and scan the barcodes of products they want to order, and then they plug the scanner into a USB port. This basically acts like a disk drive, so there's a file of scan data in a predetermined location on some drive.
The applet simply looks for that location and uploads the scan data, if it finds it, and then forwards to a "review" page if it found data and an "error" page if it didn't. The GUI is simply a JLabel which says "Searching for scanned data". We're just using a plain vanilla <applet> tag to load the thing. So it's just about the simplest possible applet (except that of course it has to be signed). I don't work in support but I haven't heard any feedback that people are having problems with our applet.
we also using applets in a stock exchange site to display the graphs and currency changes. it run out of browser like a swing application. we may use webstart for this(more secure compare to applets i studied some where). but my seniors are restricted to use it.
