The email comment makes no sense. If someone is so adamant they need a specific email address, what else will they be unreasonable about? I'm more interested in whether the company does everything possible to make the office a place you never want to leave. The right equipment for every job should be default. Food follows closely after, followed by nontraditional work spaces. Some of my best work is done either standing at a desk or sitting on a couch with my feet up. Flexible schedules also seem more important than an email address.
Anonymous fingerprinting sounds like a more sensible solution than something that allows advertisers to build a profile about the user of a phone over time like UDID.
