I thought "bloatware" referred to "unwanted software included on a new computer or mobile device by the manufacturer." Like, for example, the Wild Tangent Games on my poor old Gateway (if I recall correctly, I only clicked on the shortcut icon for that once in the six years I used that computer).

Turns out that's actually the second definition, the primary definition being "software whose usefulness is reduced because of the excessive disk space and memory it requires."
