The new treo 680 has 64 mb of usable memory. My existing Treo 700W has 60 mb of usable memory. I know they are different operating systems, but how much more available memory will the 680 have after installing Goodlink than the 700W? (my 700w still struggles along with 3-6mb of avail memory which causes it to crash often and not run much anything other than Goodlink).
