I rely on the red squigglies in word. What happens when I author blog posts? How about typing in gripes to web forms on web shopping sites?
Now, I do have to remember to click the IE Spell button, but it beats copy-paste into Word, copy paste into notepad to remove all formatting, copy-paste into my Blog.
Get yourself a copy now (and don’t forget to donate if you use it… it keeps the author making new software).
