The cap really don't make all the difference, I think there are very few people downloading over 1,2TB/year.
The only issue might be if I'd have a very busy month, and need to download 150GB, I'd have to spread it over 2 months.
In Belgium ISP's are just plain stupid!
There's a 15GB limit,which is way too little even for the average internet fan. In order to download your material you need to download the first 10-15GB on highband. Then they set you on lowband.
You basically will be using internet 24/7 on lowband to get an additional 30Gb downloaded per month; or, pay eur. 27 per month extra (which is outrageously much for many).
Imagine you're running a business and you just capped 100GB,you all of a sudden can't receive any mails anymore?
I hope the ISP will understand this and not cut but lower internet bandwidth instead to say dual ISDN speeds (112kbs up/dn)
On high times (and I view a lot of streaming TV) I use upto about 45-50GB download a month, that translates in viewing TV every evening after work for about 2-3 hours.
On low months I'm not using more than 2GB.
For the end user 100GB should be enough, and whatever is getting close to the limit can always be downloaded a next month.
Though I agree that I wouldn't want ISP's to make abuse of it, and keep on lowering the monthly limit.
