I really hate advertisements on software GUI's it's a cheap trick and uncalled for.(even when we are getting the software for free. It puts me off purchasing the software.
Disagree: the special-priced upgrade to a version with OCR is worth a mention. All I'd ask is that the advertisement disappear once the sale is over. Put it another way: if the special price upgrade was on offer, and I was NOT told about it, I'd be angry.
