If you were an O2 customer, just like BE, you would of most likely enjoyed around 1.3Mbit upload connection speeds. Just looking at everyone's upload connection in their sigs suggests that it is fixed at about 1Mbit on Talk Talk, just like it is on Sky in my experience. However on Sky I only had 796kbps when I was first switched. They changed something which gave me just over 1Mbit on a much lower SNM. I am still 30% down however which I am not at all happy about.

I had 1.2 Mbit on BE with a 6dB profile and 1.3 Mbit on a 3dB profile on quite a long line. I wish that Sky had not purchased BE/O2 broadband or that O2 had not purchased BE broadband for that matter.

To me this is clearly to differentiate ADSL2+ from fibre. How many people would notice a larger download speed? Not many IMO but the upload speed they might notice if they upload anything. 1.3 Mbit compared with 2 Mbit is not a big difference but 1 Mbit compared with 2 Mbit is x2 which sounds much better.
