Well personally, I use an android tablet to note my stuff on the field. I am not that moved to get a computer tablet either as that kind of defeats the purpose and functions just like a netbook.
I suggest that you do the same as well. You might want to get something similar as there are a lot of tools that would let you take note of the important stuff for easier recall and structuring when you get home.
I bought a Targus stylus yesterday. It works better than I expected. So far I am very happy with the machine. I installed Homegauge, Adobe acrobat and still have plenty of room for more.
I used it yesterday and never had to plug it in. I could even read the screen while I was outside gathering all of the info I needed.
Chrome works much better than IE.
I used to think like that. Now I am much happier just doing everything once. I don’t have to think about the job once I leave the driveway.
