for general usage like surfing mail etc it's fine. For torrent too it's fine coz now you can keep your downloads/uploads open all the time. It will take three to four more hours but now you have all the time.
In fact, if you are on private trackers 512kpbs will allow you to keep a healthy ration without much trouble.
And then, don't you think that your sleep is priceless. You have got that back. :hap2:
What will su*k
1- downloading pron clips. While earlier it was a matter of ten to fifteen minutes now they will take hours. Same goes for game demos, programs and other clips
2- Video playback on YouTube and like will stutter.
