The HTC Eris Droid does not need to be tethered to use as a modem to surf the internet. It accepts all type of site and https certificates with the stock browser.
You and size the screen by simply touching the screen with two fingers and moving them apart to toward each other to magnify or reduce the screen on a web site.
You will love the phone it is a great phone. Better then the iPhone for sure as I have had the chance to use one of them too.
