No problem here. Usually mine has been on wifi because I've spent the day at home (after being away all day yesterday). One corner of my house had bad reception for my wifi and didn't even realize it when I was using the browser. Edge definitely seems slower on EDGE but not like day and night.
My house is kinda up in the hills and usually I get patchy reception via my Treo. Spent two hours this morning talking to family on my iPhone and the reception was vastly superior.
