Bank account? On my savings account (which I only keep ~$300-350 in to be able to cash my checks w/o hassles, or fees), there is a yield of .75% annual (does that even cover inflation?)! I remember the same bank used to have 5-6% annual several years back---what happened?!
Anyways, if saving, a stable fund would definitely be the right thing. You'd actually make some money.
And I'd advise to wait just a little to see how effective ATI's next product is before splurging on a GF3 right now....
