suggy, I have always used my business name in my page titles, but I also use something to identify my target customers:
Blue Widgets for [target group or use] from Acme Company
Other companies sell some of my widgets (the ones I don't make). By adding something to identify my target customers or what they use the widget for, I figure I can get a little step above others who are selling the same widget but not targeting my customers or the particular use. Also, I believe it helps pages to rank when people search on the use.
