BT-20 with ASUS 1005HA

[hoochbear]

have new ASUS 1005HA. Am considering BT-20.
Anyone with experience in this or similar combo?
ASUS has win xp home ed v 5.1.2600 sp 3.0
1 GB ram and 1666Mhz. hope to put together and confirm
this system works by end of month or send ASUS back.
primary interest is very basic: mobile GIS locating and plotting info for real estate market studies. photos of sites. having onboard Street Atlas USA plus. also any delorme packages available for download, ie Color Imagery annual subscription.
Also use ESRI Business Analyst Online. any common handling programs. ie Excel worksheets. would be a plus.
Dont want to go up to Xmap or other more advanced.
I am sold on the quality of Delorme mapping quality , just need to make sure that hardware/GIS lives up to standard. tnx hoochbear.
