Let the hive mind of Engadget get that for you.
"I just switched to Sprint from Verizon about three months ago for the Pre. Then I went for the Hero about a week ago. Now, I miss my hardware keyboard and am thinking about switching to the Moment. I am still able to switch back to Verizon if I want and get the Droid when it arrives. Should I just trade up to the Moment when it comes out, see if I like it, and if not switch to the Droid? Or something else entirely? Help!"
It bothers me that people still think the Storm is a bad handset. If you actually tried updating the firmware, you'd notice a ridiculous difference in both speed and reliability. Seriously, if you have the device handy, try updating to .151, and then think about writing an updated review of the handset. You won't regret it.
I've even written a blog post on the matter: http://www.mobilitea.com/blog/2009/07/12/upgrade-blackberry-storm-os-151/
I highly recommend updating if you get a chance. You won't regret it.
