The PN557W  stylus is nice, I like how it magnetically attaches to my Dell 7285 but just disconnects way too often. This has been an issue with most of the Dell styluses I've used but normally it's weeks in between. The PN557W  disconnects at least 2 or 3 times and hour, if you unscrew the pen, release the battery then reinsert it reconnects. It'll disconnect in the middle of a session, so I don't think it's going to powersave mode or anything. Hope Dell can come up with a solution. The best pen I've used for Dell devices is the Huawei Matepen. Too bad the price is like triple, over $100 but works great and can be charged via usb. Any ideas for the Dell PN557W ?
