I switched to Bing as my primary work search engine about six months ago and never looked back. The two things that have kept me on Bing instead of back to Google are:

1. Search results seem to return deeper to the source with Bing instead of Google. For example searches on Google seem to return to a forum where someone points to the solution, where Bing returns the solution.

2. Bing currently seems to give less credence to site scrapers.

With those two things I've found that I like how Bing:

1. Gives definitions for works better than Google.

2. When you hover over a result you get the "More on this page" feature.

What I miss the most from Google:

1. Doing math and conversions in the search field.

Archives.org isn't enough. The digital problem is more than just web sites. Every state records legal files with various methods, platforms and formats. Tiff's, JPEG's, WAV's, PDF's and more are the real heart of this issue along with web sites.

The Washington State Digital Archives (http://digitalarchives.wa.gov/) is already taking on this issue and has been for five years. Hopefully, more than just a few state will get serious about this issue.

We may have already lost files from 15 years ago, but that doesn't mean we have to loose files from this year.

(Full disclosure, I work for there.)
