Lightest and fastest go to google Chrome. Security? Isn't IE secured? Anyway, i use firefox because of its addons.
Im guessing at 22 February or even 16.Atleast it would make sense.They said RTM should come shortly after RC.
Hope the IE9 RTM will install seamlessly and not require uninstalling IE9 RC. As for IE9RC, have downloaded that and will install today. Is it correct that IE8 will then disappear and only IE9 will appear (like all other browsers where chrome/firefox updates just install on top)
