Working at home

I don't go into my company's offices every day. I work full time (and consider myself pretty lucky to have a job these days) but 4 out of 5 days a week I work from home.

This is a really ideal way for me to work because of how my brain operates. I'm very easily distracted, so the days when I'm in the office go something like this:

7:15am - This is great, I forgot how nice it is to have all this technology right here. It's so quiet and a great place to work.
7:55am - Working hard and in the 'zone'.
8:01am - Huh, what's that? What, what's that? It's everyone arriving at once in high heels and clicky shoes! (which is not the same thing as slick shoes). This one is getting coffee, this one is having breakfast (munch munch) this one is talking on the phone all about the traffic getting in this morning.
8:15am - Starting to get back into working...
8:45am - Huh, what's that? Oh that's my office mate talking about personal stuff on the phone. That's my other office mate starting up this morning's round of conference calls.
9:00am - Oh, it's snowing, here's the walk-by discussions about the weather, here's the telephone calls about when folks will be getting home from work, if they will be leaving early.
9:15am - OMG I'M NEVER GETTING ANYTHING DONE!!!!

Yeah so for me, working from home is ideal.

What about your work situation? Anything about it you really like, or really don't like? What's one thing you would change about your work environment if you had the ability?
