Gee, you likely found out that residential broadband connections are ASSYMETRICAL. Your upload speed is a fraction of the download speed. If you contract a 10 Mbit broadband connection, your upstream speed is likely 512K (0.5 Mbit).
That´s why is investing into its FTTH (Fiber to the home) experiments.
Cloud computing is indeed pretty slow until your UPSTREAM (speed from your computer to the rest of the net) is 10Mbit or higher (the sweet spot being 100Mbit, which is the same as a Fast Ethernet LAN).
Or, like Vint Cerf admitted once to me five years ago "Residential broadband users are crippled".
