Asus EeePC UMPC or netbook

Few weeks ago I decided to replace my heavy and bulky 5-year old notebook PC with a smaller and highly portable one, and so I bought my Asus EeePC 1000H.
With its reasonable price (~$500USD), I think it is worth owning one if you need a mobile computer that can perform the basics just like a notebook and is more portable (smaller form factor and ligther in weight)

This is the brief specification of the EeePC 1000H:
Display: 10.2" TFT LCD with resolution 1024 x 600
Processor (CPU): Intel Atom 1.6GHz
Memory: 1GB DDR2
Graphics: Intel GMA950 integrated
Hard drive: 2.5" 80 or 160GB
Size/ Weight: slightly smaller than A4 paper size; slightly less than 1.5kg
LAN 10/100, Wifi supports 802.11n (faster than 802.11b/g), Bluetooth
VGA port, USB port (3x)
Webcam 1.3mp
6-cell battery pack
Pre-installed with Windows XP Home edition (service pack 3); DVD for system restoration

+ points:
Good battery life, last at least 5 hours for average usage after fully charged (less than 2 hour charging time)
Decent display with adequate brightness
Good sound (Dolby Sound Room!)

- points:
relatively heavier than other netbooks on the market (due to its 6-cell battery)
only one slot for RAM
