I got one of those small netbooks for travelling - Acer ONE LO5021 with the faster AMD chip.
The spec says max 1GB RAM DDR3. Anyway I removed the 1 GB ram and replaced it with a 2GB RAM module -- these are cheap enough now. It works fine and the system really flies for what I need on the move -- even Photoshop CS5 is passable.
You might just find the 1GB RAM a bit limiing but you CAN replace these with a 2GB RAM module (around 40 USD - well worth it).
If you have one of these small ultra thin / light netbooks IMO it's worth replacing the 1GB memory with a 2GB RAM module. 9You can also put in a faster bigger HDD drive too -- easily accessible BTW - just remove 7 screws on the back panel, and the HDD drive and memory are EASILY acessible -- in fact EASIER than on my primary (Heavy) laptop.
With 2GB RAM you can also run a Virtual Machine or XP mode on the netbook too giving it significant more useability.
I'd also get rid of the Windows 7 starter and replace it with something like Windows 7 Pro or at leasy Home Premium.
