Well hopefully the 4mbps won't be too pricey. I'm thinking the 2mbps will be at the old 1mbps prices, or a little more, with 4mbps probably being laughably high.
I really hope they don't stick with 128k upload. Or at least make it a bit better. I have no problem with 1mbps download currently (use 2 VPNs constantly to the UK with no worries), but the upload sucks. Try to FTP anything and it takes forever. If you are doing anything else at the same time and it can even kill the process. Totally sucks.
Actually that was one of the reasons I went with MiVision in the first place. I heard on some of the forums that the upload speed actually went to 256k if you had it. Don't know if they stopped that or something, because I definitely don't get 256k.
I doubt they will auto upgrade all 1mbps users to 2mbps. They don't come across as being too nice in that respect. Considering they won't have a large customer base, and we would probably pay extra (I know I would) to double the speed. NTL used to do that sort of thing (I went from 600k or so to eventually 4mbps (about 3 or 4 auto upgrades) for no extra cost, infact it got cheaper, when I was with them), but then again they had millions of customers.
Cheers
