At the moment, I have a 512K service which has been promised to be upgraded to 1M free of charge.
Currently, I can download pages from almost anywhere in the world almost instantly. Presumably, this 1M service - if it ever comes :-( will be quicker. For me to upgrade to Cable means the upheaval of having an optical service connected and an increase in the monthly rent of around 50%.
What advantage am I going to get from that?
I'm not into streaming video or anything like that, so I think it's just a precursor to capture you into buying on-line streaming services. In other words, it's a sprat to catch a mackerel. But unless I can see distinct advantages, this little fish 'aint biting!
