Your contact list is growing larger every day, and so are the number of email addresses, instant messaging handles, and phone numbers your contacts use. That means you’d do well to find the best tool for managing your contacts before your contact list gets out of hand.
Gmail/Google Contacts (Web-based)
Popular for its web-accessibility and the sheer fact that any contact management system built into arguably the best email client around has a lot going for it, Gmail Contacts have a strong following. Gmail’s contact management isn’t perfect—even those who love it have their complaints—but the fact is, anything backed by Google is likely to have a huge following, which also means tons of third-party applications built to support their infrastructure. Gmail Contacts lovers are still waiting, however, for the ultimate syncing tool, and perhaps a dedicated contacts tool separate from Gmail.
