I hate to register and login for several services, such as to sync my bookmarks between different desktops and hosts, emails, mobile contact list and calendar, CRM system.
If I could merge different services into a single account with unique dashboard, I would wish to have the following:
SyncML Cellphone Contact/Calendar sync service: www.mobical.net
Business-Networking: xing.de, Linkedin.com
CRM service: SugarCRM.com
Browser bookmark sync service: Xmarks.com
