For me, my gmail gets all these forum updates, so when had push on my gmail account, it would drain my battery in a few hours
So I took off the push software and set it to check every 30 minutes
I will still get this software, because I like the idea... I just won't use it...
There are 2 other free solutions out already that I had used for push gmail... er, make that 3, if you include the one Sprint offers...
