Just kidding, I use my A2000 almost every day, either for entertainment/games/nostalgia, or to tinker with the OS (I enjoy trying to squeeze maximum potential out of this old hardware). To try to cover a few of your points:
The A2000 is a lot more "bulletproof" than many other machines. Harder to kill with a leaky battery, tons of expansion options, etc. It's easy to work on, easy to expand, and quite capable. With the Indivision ECS you can use any modern LCD monitor and screenmodes like 800x600x16 colors, 1024x768x4 colors, etc. Expansions for it are almost the cheapest of any Amiga (since they're so plentiful). Sure, you won't have AGA, but only a few games require that. About the only thing hard to find or expensive would be a graphics card, but that goes for just about any Amiga model.
You can run up to Workbench 3.9, or maaaybe 4.0 Classic if you find one of the ultra-rare PPC accelerators for A2000, and since you asked there are also a variety of IDE solutions, ranging from Zorro cards to cards that fit underneath the processor socket to add an IDE interface. But personally I'd ditch hard drives and use a CF, that's what both my Miggy's have.
Here's a few pics of mine, you can tell I love it a lot, haha.
