This web translator provides no easy means less than a browser. Just what it misses is the bookmark facility(And many more).but i thought bookmark facility would have been an important facility for daily readers.

It has native support for Windows 95/98SE/ME/NT4/2000/XP/2003 and now also for windows 7.
In reality,it integrates google translator service itself,but still i would rate it little higher on my list. (Off course keeping aside the multi languages support for google is much much more for google)
