It depends on how we treat it. Given it's versitility, I can see a lot of development going into it.
Right, now onto specifics.
Holoemitters: These I can see being miniaturised quite a bit, but their size is in proportion to the complexity of the projection to be created and the area in which the projection can be created in. "Hand-held" covers an awful lot you know, so going by gut feeling say 3m radius? Energy usage wise, I'd say comparible with mobile phones so making about 10-14 days standby and about a days worth of active usage. Of course, sticking a bunch of smaller ones together would probably work better.
Solid light holos: These I see being at least an order of magnitude bigger normally and far more energy hungry. And I see them as more specific in construction. So yes you can have lightsabers, but that's all they are. I can't see ranges being more than a metre, and probably less, for hand held devices. Anything more complex than simple shapes will need to be fully 'wavetech (i.e. sonic screwdivers).
My initial thoughts only.
