New netbook or upgrade old one?

Well, after doing some market research i've decided to stick with my >1y old Acer Aspire One and upgrade the memory to 1.5GB.
Sometimes you don't have to be ahead of the flock to enjoy what you have, actually the Acer is a fine little machine, one of the main features i like about it is its solid state hdd, which enables me to use it even in more bumpy circumstances.

Awell, here are a few links:
