What an excellent question :approve:
My answer, in a word is yes! However, allow me to elaborate :)
- TomTom, Pocket Streets and Memory Map speed up navigation (so far less time on the road between assignments and less time map reading in the hills)
- Similarly, Money means that I can update my expenses as they are incurred and I don't have to try and figure out what the receipts mean at the end of the week :)
- BillRate reduces my client invoicing time by at least half and I don't tend to forget to invoice work!
- My keyboard allows me to type up notes without booting up a laptop or pc - particularly useful when I'm on site and want fast access to files
- I have access to recent email of course (very handy at times!) and I've always got my diary (for making appointments on the fly) and my contacts.
That's productivity, but I also find my iPAQ useful and great fun: Flashcard Whiz and assorted games are great for filling in the odd spare moment practising my French or vegetating, I can view photos, listen to music, watch movies and all the other good stuff we talk about here.
On the whole, I don't think that I would want to go back to paper maps, diaries or address books and I would miss both my X50 and hx2790. I could however, forego my X3 ;)
