So now that i have mine, i have noticed that it rarely lags compared to the storm and the biggest lag was when i was getting all my service books etc....
gotta be honest it hangs up a little bit on me... when installing / dl'ing apps. sometimes i have to wait a 5-10 seconds when oepning apps. Not as fast as I had expected.
Of course it's going to be a little slower when installing or downloading apps. Are you saying when the app is previously installed, it takes 5-10 seconds to open? That doesn't even happen on my Curve. I suggest a battery pull.
So I started with 111 MB free, installed Opera Mini, did a bunch of browsing, played around on the OS, and went back to see I now had 114 MB free, lol!
