Thanks for the helpful replies.
I use a small notebook (3" x 4.5") for my main collection tool now. In the long run, it's faster to do this compared to using freeform notes or voice recording programs on the PDA, because I won't have to switch between programs to enter digitalized information into the PDA.
One thing I haven't mentioned is that I can't sync my PDA to my laptop, due to software installation restrictions. I use a wireless keyboard to type everything in, but this is not an ideal solution. So whenever I have a 5-10 minute window, I use my keyboard to enter processed projects and next actions from whatever's on the notebook, then tear the pages off.
When I get home and I still find myself with collection buckets to empty, I run Bonsai and Agendus Desktop and tear through everything in a flash. Ideally, I would have these tools available to me at work so I can process inputs while I'm still energetic, but this is the best I can do at the moment. The information I get during office hours normally cannot wait until I input it via my home PC. It is this limitation that tempts me to go plain vanilla again, because that way I won't have to wade through outlines on a 320x480 screen at work when i'm processing.
Because my PDA is off-limits in a zone 2 class environment (remember, I work for an oil company), I have a next actions context list called @Site, which I put into a section of my notebook. All other context lists (@Anywhere, @Agendas, etc.) are in my PDA.
Do you have any more suggestions to speed up my system? TIA
