I actually would have read "portable computer" as excluding a home computer, and the fact that the licence was changed to state portable only, not "home and/or portable", would seem to back that up. Licences that allow hone use are usually very explicit in that regard. I can see why Adobe might have made this distinction - a home computer is obviously put to personal use and in addition may be used by others while you are at work, whereas a portable computer is probably regarded as being an extension of your work computer and thus won't be used at the same time as your work computer. That doesn't help all those people who use their home computers to do office work, but I guess the software companies would argue that the onus is on the office to buy the extra licence for such employees. 

If you are doing a lot of work at home, get your office to fork out for another licence. They shouldn't complain - after all, they are getting unpaid work out of you. Just tell them that if they don't buy the extra licence you'll need longer to do all those jobs that they want doing urgently!
