We have tags for a number of companies that make only one type of equipment or software, like synaptics, wacom, aptana, and mikrotik. There are also companies like apc that make a range of products, but they are primarily known for one type of product and so far, that product is the only one associated with questions here.
In these cases, if the question is uniquely about that brand of the product and not generic, the manufacturer tag is unambiguous (we can assume a synaptics question is about a Synaptics touchpad device and an apc question is about an APC UPS).
There isn't a huge number of questions associated with these tags. Should we treat them like manufacturer meta tags and clean them up (which would likely mean renaming the tag to add a product designation), or ignore them?
