"Except there's a problem. When a contact emails you back, you don't see their business card. If you want to phone them, you have to jump from Gmail to Google Contacts via a series of clicks just to even see their number. This is crazy..."

Hover over the sender name in an email or the inbox and a 'card' pops up with picture etc. Click their name to see all details. 1 click, not too crazy.
