A3000 has 80mbs, A1200 has 128mbs. It uses about 10-15mbs on startup, and increases to 30-35 mbs. Though I just browsed google news and stuff, and it may get worse ...
At the moment it takes about 20-30 secs to fully render a page with some images (google news). Google entry page without any images takes about 5 secs or something.(hmm actually there's an image there, the google logo)
