While a vast improvement on the past, "Navigate to" doesn't find stuff intelligently like Resharper's jump... e.g. if I have a file "LabListView", I can type "llv" in the "go to" window and it'll be highlighted (I could type any combination of characters but I tend to use the capitalised letters). VS2010 just shows an empty list when I do that -- I have to type a complete partial name.
I could also be imagining this, but I have the feeling Resharper remembers which files are related when I select them from this list because if there's more than 1 match it almost always seems to have the right one at the top of the list based on my current context.
FYI, Eclipse also does partial the way Resharper does out-of-the-box: semi-partial and abbreviation.
I believe Eclipse also does "best match based on previously opened files" (sort of heuristic/guessing) just like you guessed the way Resharper does it.
I wouldn't be surprised if Resharper added Eclipse's features that are missing from VS.NET being that JetBrain makes IntelliJ that competes with Eclipse.
Of course the best part of Eclipse is that it's free and you get everything :)
