Bing is not horrible

I've been playing with Bing for the past two months or so; I made it the default search in Firefox for research purposes.

After 60 days in the saddle I will say that Bing is ok for my casual searching, which is about 80% of my search time. I do find myself loading Google several times a week to get better results. Here are the places Bing appears to fall short in that 20% of the time where I switch to google

• Google filetype: and site: search keywords are genius and irreplaceable.
• Bing seems more focused on shopping-related results rather than pure research
• Bing's interface is pretty rather than clean; I prefer clean.
  

I'm going back to Google full time as it meets all my needs. I wanted to make sure I gave Bing a fair shake.
