I have used Blackberries in business since the beginning. Fantastic products!
Sadly after spending the better part of Feb 6th transitioning from Torch to Z10 I have had to abandon the effort and request an RMA number to return the Z10.
Here is why:
"Link" appears to be focussed on syncing documents and media like content such as music and movies but does not, from what I can tell, sync Outlook Contacts, Calendar entries or Tasks. I have never bothered putting music or movies on a BB... never had the time to fuss with such... however, I use, edit and sync my Contacts, Calendar and Tasks between my Torch and my desktop PC every day... as in EVERY day!
From a review of postings on various forums there does not appear to be a solution in the works to this problem and the trend appears to be to use a Cloud based email or service to host such "PIM" information and then sync the handheld to the Cloud repository. This method MAY be suitable for some forms of info but it is not suitable to post such personal info on the cloud... it needs to stay on the desktop and in the handheld device, both of which are password protected and looked after carefully.
This is an odd situation, BB (RIM) cut their teeth on pages, emails, BBM and great cell calls, mainly in a business environment. Many small business users live and die on their BB. They do not run Exchange Server... they run Outlook stand alone on a desktop. To remove this functionality from the Z10 (BB10 overall perhaps) seems at best to be a serious oversight.
I wish BB the best with the Z10 and hope to see it do well. For me, I had to make a choice between the efficiency and effectiveness of syncing Outlook Contacts, Calendar and Tasks with the Torch, or hand feeding and maintaining thousands of constantly changing entries into what is undoubtedly a more powerful and wonderful looking Z10. Efficiency and effectiveness won over brawn and beauty. The Torch is back on line... It's a tool... a really great tool! Tomorrow it will process a hundred emails, numerous SMS messages, a few BBM's, keep me on time and feed me a bunch of useful phone numbers and addresses as it has for a couple of years now. It will also spend an hour or so teathered to my laptop at a remote location where there is cell coverage but no internet. It will NOT display any movies, tweats, twits, or facebook stuff that I won't have time to look at anyway. The fast, powerful, shiny Z10 is heading in an RMA bag back to Telus.
I have a sort of sick feeling in my gut and hope to be able to sync again in the future!
I wonder if we will ever see a customer focused response from BlackBerry.
