The HTC Hero is fairly old. I keep one around because it's quite slow and if I can make something function fast on it, it will run exceptionally well on new hardware.
On the tablet you can use both a wired and a Bluetooth mouse (I've used a wired mouse and Bluetooth keyboard simultaneously). You shouldn't have to worry too much about the mouse as it is considered "fake touch" and just acts like a simulated finger event. Check out the "Touchscreen" section at this link to understand how to support it: http://developer.android.com/guide/topics/manifest/uses-feature-element.html#hw-features What you might want to test out is a tablet or phone with a Bluetooth keyboard with directional keys. I've run into a few apps that I wanted to use the directional keys on my Bluetooth keyboard and it wouldn't function properly. If you plan on doing apps that take a lot of input (like typing information in), your users will thank you if you support navigation via the keyboard. I'm not fond of having to constantly touch the screen to change input boxes when I have a tab and directional keys available. Some of the specialty hardware, like the Sony Xperia Play, have controls that take special consideration. I picked one up to make sure I could test things properly on an actual piece of hardware. Some even have special SDK add-ons available via Eclipse or from the manufacturers sites. It is one of the things that makes Android more challenging to code for, but I personally enjoy the challenge. It also gives us, the consumers, a lot of options and doesn't force everyone to be the same.
