This is an e-mail terminal with an excellent display and a poor camera. It's also a good media player for music and video, but it's let down by many software bugs with new ones appearing as old ones are fixed.
When I got the phone in Feb 09 it crashed regularly, until it had major software updates. The update process is scary, taking 30~60 minutes during which time you wonder if the phone will be turned into a "brick".
Roxio media manager, supplied with Blackberry Desktop Manager for transfer of pictures and music between the the phone and a PC, is slow and a resource hog. The update manager which comes with Roxio has caused slow boot problems on many PCs I've seen. Use MSConfig to disable start-up of ISUSPM to cure this problem. Set the phone into Mass Storage Mode so it appears as an extra disc drive when connected to your PC, and you don't need Roxio.
Be careful when picking it up: if you grip it "top to bottom" the back cover comes off - it has very fragile looking clips to hold it in place. When removing it from the holster you cannot help but press on the LCD, leaving a distorted region on the display for a few seconds - does this help the display lifetime?
Sept 09: now with the latest software v184.108.40.2061. It is much more stable, but has a new problem. The time to scan the media card and display image thumbnails is very long. I have an 8Gb card in the phone, with only 100~200 stored photos. If the phone has been connected to a PC via USB, the media card scan takes ~5 mins before you can view any stored pictures. If it's been rebooted from a battery pull expect 20+ minutes before it's completed scanning the card. Scrolling through thumbnails of stored pictures is painful as the update rate is so slow - no flicking through dozens of pictures iPhone style on this thing.
