With the amount of available memory you still have available you really shouldn't notice that much of a difference but of course, we know in real world terms, that just isn't always the case. As Daphne pointed out, animations, for instance, are going to be slightly taxing on CPU/Memory more so than just a run of the mill, clean and simple them.
I've found this to be the case as well. Especially on older Blackberrys like the 7105t. I'm guessing that theme size and add-ins like animation or weather checks will effect performance, but the more powerful processor used now vs. used back in the 7105t days overcomes most of the performance hit. But it's still there. It would probably crop up if you had a lot of apps open and were taxing the system.
