I got a new toy yesterday - a BlackBerry 7290 PDA. It's a pretty fun gizmo, and the fact that it runs J2ME is icing on the cake. It comes with desktop software (Windows only :-() that syncs your PDA data with other PIMS such Outlook, Lotus etc. For a company that does such a great job of supporting Java, it's a shame they don't use Java on the desktop to provide x-platform sync.
The Blackberry service also comes with a bundled online email (BlackBerry Web Client) that will gather up mail from several sources (POP and IMAP) and forward to your BlackBerry.
It's a neat service - but I can't help but think that RIM has missed a golden opportunity to enhance the "stickiness" of the BlackBerry. What I really want is the equivalent of Plaxo for the BlackBerry (or alternatively, I want Plaxo to support online wireless sync of my PDA). The thing is, I don't want to manage my contacts on my desktop - because my "desktop" moves around a lot (SunRay, laoptop, home PC, etc.). I want my contacts online all the time, accessible from everywhere, and safely backed up.
RIM and Plaxo would make great partners.
