Contacts Database Size

Loving my new HTC Desire having finally defected from Windows Mobile, and PalmOS before that.

After 3 days I had already run out of application storage memory, having got used to just sticking stuff on the SD card even if I didn't use it on my Touch Pro! However by deleting stuff I don't use it is not a problem - I have 50mb out of 150Mb free now. Considering rooting, and custom Roms but not yet.

But I notice that my Contact Database takes up about 10Mb. Is this normal. I have about 300 contacts and most of those are just email's from Gmail.

Great Forum, been reading lots of stuff.
