I never had a contact lost, nor lost an SMS, nor had Wifi or GPS turn on randomly. That's on three Androids, a MyTouch 3G, a Droid Eris and a Nexus One. I found these problems I simply cannot replicate nor have don't see anywhere else.
Only way you can force Wifi or GPS to randomly happen is by touching the screen with the activating widgets on the surface. This can happen accidentally through various means, like putting the phone in your pocket or holster without turning the screen off. It can happen on a tight holster or pouch, or if the phone is inserted into a bag with lots of stuff on it. Doesn't happen on the Storm because a stronger pressure is needed against its screen to activate. But of course, you can take off the widgets off the screen, or simply always remember to lock the screen before you put the phone away.
I have Storms in the household. Its probably the worst device in the world to type on. The one BB user in the house was so happy to switch out from that phone to a Bold2.
I find the internal memory for installing apps way too limited on the Bold and Storm. On the newer phones, like the Tour, Bold2 and Storm2, the amount of internal memory has improved over older phones but only reached to the level as the --- get this --- original HTC Dream G1 --- which had 256mb. The average Android on the market now has 512mb. Its interesting to note both Android and Blackberry apps in a general range, seem to have about the same memory requirements and rarely exceed over 1mb.
The result of low internal memory runs down quickly the moment you start installing various apps. It gets worst because the email is saved on this internal memory. I hit the low memory on my Blackberry Tour when I was getting pushed email that had document attachments.
Also, when if the Blackberry turns nuts, its a battery pull, followed by a long reset and boot up. On the Android, it only does a UI reset, no battery pulls, and a fresh UI is up in seconds.
On the Blackberry if the black clock appears on the middle of the screen with the arm moving, you wait. And wait. On the Android, if your app is hogging the screen, a message would flash asking you if you want to force terminate it or wait.
The Tour and earlier Blackberry depends too much on the trackball for navigation. Easy to gum up. Had these issues which I had to take to the dealer to clean up. Not a problem on the BB with optical trackpad. Certainly not a problem on Android.
Great multitasking on the BB, but I find it tiresome to hunt down open apps by opening the task manager, and to close down each app deliberately through the side menu. On the Android, you can leave them and the OS will shut them off by itself. This one feels like you got an automatic transmission with your multitasking while the BB is a manual transmission.
Low memory error caused a Software 552 on my Blackberry Tour. Found a way to restore it but by then I lost confidence on the phone after using it for five months. I'm not willing to pay for a more expensive data plan on a phone that had issues like this for another year when a Droid Eris, not only has a cheaper data rate (half the cost for me) but a far faster and smoother browsing experience, more apps, more apps it can store, cheaper but better quality apps for the money, with a simply more responsive UI on an OS that doesn't crash.
This is not to say I wasn't happy with my Blackberry Tour. I was, for the most part. I love the keyboard especially on the Tour, smooth text entry isn't something the Android is good at. But by the end, it was time to move on to something better.
