PDAs are kind of dead, but the Dell (Because it's fairly cheap) isn't a bad one to find this out with.
Ok that's not true, PDAs are great for a lot of people but what I found was that, as a student, the PDA was just the ultimate compromise.
-Too large to easily carry (Not pocketable, screen damage results from pocket carry anyway)
-Too small to comfortable use for a long time. I did have a keyboard and used the thing exclusively for History notes, but a Laptop would have been better.
This lead to 2 problems:
Not convienet to carry, not convienent to use. MUCH faster to jot down a note on a 3x5 and enter it into my comptuer later or something.
The thoughts of using it as a universal remote or for surfing the web wirelessly sound great, but after about the third time you'll realize you like a real remote better, and surfing the web on a 3x5" screen just isn't the way it was intended to be.
With that in mind I have found the ultimate PDA--My Sony Ericsson T610 cell phone.
Bluetooth means it syncs with my computer without cables. If my computer and cell phone are within 6ft' I can sync. When I dock my iPod it syncs all my info to that, as well as the phone. I don't have to worry about another cable, it can just be charging and it will still sync.
T9 text entry with hardware keys is MUCH faster for creating appointments, etc. than the PocketPC methoods ever were.
Because it's small, my phone is always with me. My PDA sits at some 95% of the time.
If your primary objective is to take notes, well, I have a laptop for that now. It's not bad to take notes on a PocketPC, just make sure you get a Stowaway *full size* keyboard. The third time you have to hit a modifier key to enter a number is 2 time too many.
Sooo in short: Stop and evaluate what you want a PDA for. If possible, you might consider a high end phone instead (Or even a phone-PDA like a Treo). The phone is likely to get a lot more use than a PDA, which will has a big chance of being a big paperweight in a few years.
Last thought -- if you want to modify every little thing on your PDA, at the expense of having it run slugish and, well, like Windows, than a PocketPC is the way to go. If you just want a dang good electronic address book and calendar, Palm is the way to go.
