Online Saving Interest Rates Dropping; Still useful to save?

It seems like with the bad economy, saving interest rates are dropping like a rock. My GMAC Bank account has gone from 3.25% to 2.5%, and I have a hunch it will go lower. Others have gone down to 1.8%, such as EmigrantDirect, which used to offer the highest in the nation. Such a shame that it's gone down so much...

Despite the fall, it's still good to save in these accounts. First of all, you at least get 2.5%, which is better than 0% that many checking accounts offer. Having a separate online savings account also allows you to save your money instead of spending it all because it was in one pot. Online savings accounts also let you link multiple banks to transfer in/out of (imo, GMAC Bank is the easiest to use and add accounts to, and is fast in transferring!), which could let you move money between accounts that do not offer ACH transfers. Just have some money in there, execute a transfer from account #1 to online savings, and then do another transfer to account #2.
