Xobni + Launchy to replace Google Desktop
I used to love Google desktop, the mail search feature it provides is way faster than Outlook's search function, it also helps me quickly have applications located and launched, it helps to find some files on my disk in a few occasions. I don't use the bundled sidebar of it.
However Google desktop search doesn't do it's major job "search" as well as its web search. The results it presents are not good enough, and for some keywords, it's just not relevant at all. It can't correctly locate some application as well.
When I found Xobni and Launchy. I decided to unstall Google Desktop. Xobni do the same quick mail search and it does a lot more by listing interaction data and attachments. Launchy can locate applications much accurately and get me out of the headache of finding the applications when Google desktop failed me.
I still do not find a replacement for disk files search, but I still don't want to keep Google desktop, it doesn't find me the right file most of time anyway.
