"Take a look at Google Groups or GMail".
Well after looking at my inbox, Gmail has managed to intercept 1282 spam messages in the last 30 days. I virtually never hear of mail going missing and approximately one (1!) spam message gets through the filter. Pretty good detection rate, I'd say. Granted, it'd be nice if they could do a little more to stop it in the first place.
You've gotta remember that Google are one of the most scrutinised companies out there. BT/Phorm have had an infinitely easier ride in comparison (until now). They can only get away with so much and their user base is entirely free to choose another service at the drop of a hat. If enough people change their default search engine, Google is hit hard.
That's not quite true for BT (or MS, Apple or a number of other companies that enforce a lock-in of any kind). Granted there's cable/Linux. But it's a damn site more expensive and/or time consuming to change from BT lanline to cable (if it's at all possible) or to change OS compared to simply switching to one of Google's rivals.
E.g. I use Live Maps quite often because it shows train stations. And I'm free to do so, even though I use Google Search and Gmail. I use del.icio.us instead of Google bookmarks because it fits my needs better.
Privacy-wise, Google just can't afford to screw up or there'll be outrage. It's tough at the top and the bigger they are, the harder they fall.
Next up... Amazon? It'd be a hefty trojan horse for G Checkout, but they could tie it into Orkut and Books (and maybe eventually Video (for sales)/YouTube(for previews)) in the same way that they'll presumably tie Expedia into Maps.
If they do indulge in these tie-ins, they need to be extremely cautious of straying into the incestuous eBay/PayPal territory of gradual exclusion of all external parties to the detriment of the service.
Ms Hilton can't decide if she trusts Google or not.
