I have one and love it. It doesn't dry as much as it washes, which is a pain sometimes, but I only dry what I have to anyway, so it only matters when it's raining and the heated airer is not big enough to hold everything.
The big advantage (apart from space) is that you can put in a (smaller) load of washing and have it dry when you get in/get up in the morning. That was a godsend when I had children who needed PE kits or uniforms at short notice and I was working. I could save the bigger loads for weekends.
For various logistical reasons I can't do this, and with two of us I don't really need it any more, but I think the best combo for a family would be to have a washer/dryer and a separate tumble dryer, so that you keep the 'all in one' option but can also dry in one machine as you wash in the other.
Mine is a Bosch, too.
