How much available memory do you have?

[tokuzumi]

RAM, that is....I had to download a program from the market to view available memory, but I have 192 total, and I'm using around 155-160mb all the time. That leaves me with ~30mb of spare RAM, which isn't too much better than my mogul. While the phone doesn't have issues running programs, I'd like to up the available a bit.

Currently, the only applications running are HTC Sense, People, and Dialer. If I close the people and dialer, it makes about 0 difference to the available memory. The only thing on my home screen that needs to refresh is the large clock, with the weather, and the htc stock widget, which takes up the whole screen. I'm just curious what uses 160 mb of ram on my phone?
