It's really just an IBM-XT motherboard installed in a carry-around case with
a built-in monitor.
The motherboard still has eight expansion slots, but two of them are blocked
by the floppy drives, and cannot be used.
It's portable, but there are no batteries, you still have to plug it into
the 110VAC outlet. 

The 5155 was little competition for the Compaq Portable computer, which was
released one year prior, costs $700 less, but had the same CPU and ran
just as fast.
It was advertised as being 100% IBM compatible, and even weighs slightly less. 

This wasn't IBM's first portable computer, that would be the IBM 5100,
released in 1975. 

Excerpt from the original announcement letter: 
The IBM Portable Personal Computer 5155 Model 68 consists of a lightweight
case with a carrying handle containing a built-in. 9-inch, amber composite
display, one 5 1/4-inch double sided diskette drive (with space for an
optional second drive), and two IBM Personal Computer attachment options
(diskette adapter and colour/graphics adapter).
The unit also has a new, lightweight keyboard and a universal power supply.
The system board is the same as that of the IBM Personal Computer XT with
256Kb of memory that is expandable to 512Kb using the memory expansion option.
Five expansion slots are available for the connection of most IBM Personal
Computer options.
The system has identical function and performance characteristics to an
equivalently configured IBM Personal Computer.
