Definitely don't feel it's useless here either... I use it on a daily basis for quick lookups for conversations, and even in meetings I find it's faster to search on the phone than most of my coworkers can find it on a PC, lol.
Also, I wouldn't call it a daily use, but I frequently use the Local Scout feature if I need to look up "yellow page info" for businesses or get directions to the nearest store. Local Scout is probably one of the best hidden gems of Windows Phone.
Lastly, I haven't used Google's malware-poisoned search results in 3 years, and honestly, I don't miss it.
