From one Optimus V owner to the other, you only get roughly 178MB of app memory in the internal memory. Google maps takes up 10.25MB. Voice search 4.42MB. the market 3.54MB. Bloatware(carrier installed apps that you can't remove unless rooted)a little over 10MB. I have Gmail-that,s 4.47MB,and amazon appstore 2.65MB,and Extended controls 2.74MB as well as the theme pack for it 3.55MB,and Launcher pro 3.11MB,and TV.com 2.71MB, and Juice Defender 2.13MB, and speed channel 1.5 etc. etc. etc...as you can see you can eat up your available internal memory real Quick. The advantage of moving apps to the SDcard can be easily seen. there are several apps that will allow you to move apps to the SDcard on the market. I personaly like App 2 SD as it can be moved to the SDcard as well
