I have been using the 6100 for over a week now and it has been "Johnny on the spot" on everything. I have had no flaws or no complaints. I have had plenty of cell phones in the last 6-7 years and the 6100 is by far the best phone I have ever used. If a person is getting a delay on things...it could have to do with his signal. But, the phone itself is A-OK. I am sure there are better ones out there. But, this phone is fully loaded and the price is nice. The only concern I had when I got the phone is the standby time. But, it turned out to have a good standby. My wife had hers on for 6 days and it has 3 bars out of 4. So, that is not too bad. Also, I am planning on getting a back up battery...once they have a desktop charger for the 6100 with an extra slot for the battery. That way, you can charge your phone and the extra battery at the same time. Being the phone is a fairly new product they don't have a desktop charger made for it yet. But, I would say one should be out by 05'
