Had you not already decided you're definitely abandoning the telephone, I'd have suggested getting a non-fragile handset (I've used the same one for five years, now, and I'm hardly gentle with the thing) and a desk charger stand for it. Then get in the habit of using it as your alarm clock and it'd always get charged up. You could put it on pay-as-you go and set a quarterly reminder to check credit.

If you're adamant that you don't want a mobile (and frankly I'm going the other direction; I only keep the landline for ADSL) I suggest a Victorinox Cybertool to fill the space, if you currently lack a multitool.
