Some more interesting ideas from Google's Analyst Day presentation.
In a world with infinite storage, bandwidth, and CPU power, here's what we could do with consumer products.
Theme 1: Speed
Seems simple, but should not be overlooked because impact is huge. Users don't realize how slow things are until they get something faster.
Users assume it takes time for a webpage to load, but the experience should really be instantaneous.
Gmail started to do this for webmail, but that's just a small first step. Infinite bandwidth will make this a reality for all applications.
Theme 2: Store 100% of User Data
With infinite storage, we can house all user files, including: emails, web history, pictures, bookmarks, etc and make it accessible from anywhere (any device, any platform, etc).
We already have efforts in this direction in terms of GDrive, GDS, Lighthouse, but all of them face bandwidth and storage constraints today. For example: Firefox team is working on server side stored state but they want to store only URLs rather than complete web pages for storage reasons. This theme will help us make the client less important (thin client, thick server model) which suits our strength vis-a-vis Microsoft and is also of great value to the user.
As we move toward the "Store 100%" reality, the online copy of your data will become your Golden Copy and your local-machine copy serves more like a cache. An important implication of this theme is that we can make your online copy more secure than it would be on your own machine.
Another important implication of this theme is that storing 100% of a user's data makes each piece of data more valuable because it can be access across applications. For example: a user's Orkut profile has more value when it's accessible from Gmail (as addressbook), Lighthouse (as access list), etc.
Theme 3: Transparent Personalization
The more data, access, and processing Google can handle for the user, the greater our ability to use that data to transparently optimize the user's experience.
Google Desktop w/ RSS Feeds is a good first example: the user should not have to tell us which RSS feeds they want to subscribe to. We should be able to determine this implicitly.
Other potential examples: User should not have to specify the "From" address in Google Maps; user should not have to specify which currency they want to see Froogle prices in; user should not have to manually enter their buddy list into Google Talk.
