That's partially up to you and partially up to whether or not the device is suitable for your needs. Only you can really answer to those two points and to some degree, you really just have to try using one to see. Obviously, the device will only benefit if your're comfortable and proficient at using it. I highly recommend reading up on shortcuts and tips and tricks. You can definitely use the trackwheel for everything but you'll be significantly more efficient if you use the shortcuts.
Blackberryfaq.com is an incredibly useful reference, btw.
