Oh man.. 25 ft!? That's great! When I had mine for a short time, mine started flaking out at about 8 ft. I ended up returning mine because I didn't like the keyboard. I think because of the super low profile, Logitech changed something on the keyboard. It sure doesn't feel like my corded Logitech keyboard or even the other cordless keyboards that I've tried. It's like the keys aren't very sturdy and if you hit the keys from the side at all, the keys seem to stick or hang up. YMMV, but I didn't care for it and ended up returning it. It's lovely to look at though and the idea is fantastic!!
One spooky side note. I was going through some old receipts a month or so ago and came across my return receipt for the Freedom Optical. I had returned it the night before 9/11. I hope that wasn't a bad omen or anything..
Anyway..
