Is IE8 ready for corporate enviroment?
Solution 1:
Please don't upgrade Internet Explorer 6. Look at this site: http://www.saveie6.com/
Jokes aside, Internet Explorer 8 works very well for me. I installed it on many computers and all the web applications still work without problems. Don't forget: there is always the IE7 compatibilty mode, if you have intranet applications which have problems with IE8.
Solution 2:
I've been running IE7 and IE8 since their early betas (which weren't very stable), and I can assure you that as long as your internal web apps work fine under IE7 then you will have no problems with IE8.
Also, as a web developer, anything that you can do to upgrade from IE6 would be a tremendous help.
