Shameless abuse of my flist.

If anyone could offer up some advice, that would be amazing.

I am looking at purchasing an external HD for my computer. I have an iBook G3, 30GB, which I keep filling up. Right now, I have 3.63 GB free, for example.

The thing is, I might be getting a new computer in the fall. I'm a Mac girl, though and through, so I'm not really looking at picking up a PC. I'm trying to decide between:

- A new laptop (probably a MacBook, unless I come across some crazy deal for the Pro), or
- A desktop, probably an Intel iMac, and a wireless card for my poor little G3.

- I have found a limited number of LaCie 250GB externals available for $170. Mac/PC compatible, but they are, however, USB 2.0 only.

Would the external still be a wise purchase, given that I might be picking up a new computer? Does anyone have any advice as to which path to follow?
