Manx does support memory watchpoints.  The Lattice debugger takes a lot more
memory when you start debugging a large program, because it starts dumping
lots of stuff in a temporary ram file.  It also takes memory because it has to
load the 650K executable in, while the MANX one only loads a 150K executable
and reads the 100K file off the disk (Well, on my harddisk, the MANX is faster
- on a floppy, I guess the Lattice would be faster since it uses more ram)

and doesn't read the structures defs off the disk.  I would be interested in
knowing how large the program was that the reviewer used to do his test.
