I recently sold my HTC Mogul for a BlackBerry 8830 World Edition. I loved the phone but just got tired of all the soft resets and lack of memory. The hardware was poorly equipped to handle WinMo 6.1 and lagged consistenly.

    So now I'm a BlackBerry User aka Crackberry Addict whatever you want to call it. First are the pros.
Loving the sleek look and ability to customize themes. The OS is very snappy and one handed use is, of course, much easier than with the Mogul.

    Things that I'm not too happy with are:
The lack of customability compared to WinMo. The 4.2 OS doesn't support editing Word documents or html email. This surprised me as the BlackBerry is regarded as an email first device. Dealing with html email is a very ugly process. There is also a huge lack of freeware compared to WinMo; quality applications are expensive. The bluetooth is also locked down and obex isn't possible.

    Other than that however the piece of mind RIM gives me is welcomed with open arms. I'm no longer worried about my phone freezing up when I receive a phone call or having to reset the phone due to all the free memory being full.
