well, i bought a desktop computer for home first too. and it's a nice one. but i found that i was always needing the computer to be somewhere i wasn't. :chuckle
so then, i thought about having a computer to take with me everywhere i go. so i got the laptop. and for a while i did take it with me to school, to dr. appts with the kids, etc.
i didn't use it that much when away from home but boy i love sitting in my recliner finishing my assignments rather than at the desk with the big computer.
i got the pda mainly just to try them out and see what i would actually do with one. didn't spend a lot of $$$. i bought a sony clie and it cost me around $100 with a $30 free gift card
from best buy because they had made a mistake in their weekly ad. so all in all, $70.
and it's okay but i will eventually purchase of of the 'larger' models that have recharable batteries, larger memory storage, color screen, and faster processor thingy.... the next model i buy will also have microsoft word and a portable keyboard.
so i guess it would depend on what you are wanting now. if you are wanting to take something to class to take notes with instead of hand writing........ i would suggest a GOOD pda with the portable keyboard. you can link it to the desktop and synchronize them so they (desktop and pda) stay updated with the same information.
i'm prolly sounding about as clear as mud so i apologize in advance. :chuckle
