Only your needs can answer that question.. After my laptop crashed I transferred everything to my BB so I do work alot more from my BB but I still use my laptop just not as much. 4.5 also contributes to that alot to HTML, DTG, but I do need my laptop for some things.
Of course that is only something you can decide.
8830 -> 8330 -> 9550 -> 9650
Just think about how far BlackBerries have come from then till now... And what else is coming.
