Why is Internet Explorer so slow? It may be because of Bing

Quote from the official Google Blog:
"As we see it, this experiment confirms our suspicion that Bing is using some combination of:

• Internet Explorer 8, which can send data to Microsoft via its Suggested Sites feature
• the Bing Toolbar, which can send data via Microsoft’s Customer Experience Improvement Program"

Now think about it. How could Internet Explorer be so slow unless it is sending tons of information back to Microsoft to add as search results to Bing. 

My suggestion: Chrome
