I like almost every aspect of the Portable, except that silly battery design. Why in the world did Apple make you HAVE TO keep that enormous battery in there at all times. And without it, unless you have a PB100 adapter hack, you cannot use the Portable. And even if you buy a refreshed battery pack, you have to be very careful because it's easy to make those kind of batteries go brain dead in short order. But even if you care for the new battery, all batteries die over time. And since the Portable is to heavy to be truly portable, it means you would normally use a power adapter most of the time.

So if the Portable could be rewired to safely use an AC adapter, I think it would be a great machine, even if you wanted to keep it in storage for long periods of time like other classic Macs.
