It also shows symbols or numbers as you prime, install a cartridge, set the clock, and set basal rates. At first, I used a calculator to keep track of my insulin usage, but now I know that under normal conditions, a cartridge lasts me about eight days. Once in a great while, I just ask my husband to check a number, or to double check my readjustment of my basal rates. I rarely miss this display. The clock is also set by counting beeps.
Many people place the pump in a pants pocket or on a belt loop.
I prefer wearing mine tucked in my bra or in a shirt pocket. It doesn't hurt to roll over on it, bump it or anything. I've gone swimming with mine, hiking, shopping, dining and more. I would put it in a bag that I could hang on the faucet, or clip to a shower curtain, and yes, the tubing is long enough to allow plenty of room for moving around. It's a weird feeling when you catch the tubing on something, but it takes real effort to knock out the cannula.
