The eee pc is not a weak little computer. The CPU is ok and the ram is also very good if you upgrade it. Also the flash hard drive is very fast at loading large files. If you install a SD flash card you can expanded the storage space as well. But with a 9" screen eee pc coming in the future I would wait and buy the new model coming out around the end of this year.
