I have an XA and I do use it from time when I have to cut back on taking or carrying gear. I have found it to be superb in the lens department and surprisingly the camera's meter is very good with most lighting conditions. When I'm using the XA this is the only meter I use.
The only problem I have had In 9 years is the foam light seals which have recently dissolved. However, they are easy to replace yourself and this can be expected to eventually happen on a camera of this age.
Personally I wouldn't use the XA as my only camera as I would miss the versatility of interchangeable lenses on say something like a Nikon FM2 or an OM1 - both of which are compact SLRs. But for an affordable quality carry in your pocket fixed lens rangefinder with a good on-board meter it is a hard one to beat.
