While I agree that there are tremendous differences in functionality between a laptop and a BlackBerry, there are enough similarities that I don't think the OP's question is entirely
BlackBerry long-timers, you can pretty much skip the rest of this, since you've already experienced this (or something much like it). For those considering the development of a BlackBerry addiction, though, the following might be helpful
I travel a lot, and whether I'm traveling or not, need to be reachable both via phone and email. One of the advantages of the BB is that I remain reachable without bringing my luggage along; previously, a cell phone alone would provide me a measure of connectivity with the rest of the world, but a full-blown laptop was the only way I could be "completely" connected.
The BlackBerry changes all that. I have ready access to all of my email accounts and can easily respond to messages received. I can browse the web if I need to, and I still have the ability to reliably send and receive phone calls in a highly portable package.
In other words, even though I'm tied to work, I'm free.
Earlier this week, I needed to bring my mother to the hospital for surgery. I'd only had my BlackBerry 2 days at that point, and wasn't completely comfortable with its capabilities. I decided to bring my laptop along as well just in case I needed to do some serious emailing.
What a waste. Not only did I nearly lose my laptop (left it in the cafeteria), but I certainly didn't need its "advanced" email and contact management capabilities; everything I needed could be done on the BlackBerry. Not quite
as quickly, mind you, but every bit as effectively.
Yesterday, I visited her at the hospital again. This time, I left the laptop at home, and used the BlackBerry exclusively. I fielded a number of emails, kept a teleconference appointment, and handled a couple of phone calls without taking significant time away from my mother. It was wonderful
knowing that I was able to stay on top of work while still providing my mom with the support she needed.
Sure, there are many things that can only be done on a laptop: updating spreadsheets, composing lengthy/heavily-formatted documents, generating PDFs, image processing, software development, etc. But when you're in a management position and need to keep in touch with clients or staff, you can do 95% of what you need to do with just this one miraculous little device.
So I would rephrase the question a bit:
Q. Is a laptop better than a BlackBerry?
A. Sometimes. But not as often as you'd think . . .
