depends on how many keyboards will you be switching to. I started using Dvorak and then later gave it up for the following reasons:
1) it was not supported on Linux/Unix back then
2) Switching to my wife's laptop (which had Qwerty) was uncomfortable
3) my wife couldn't use my laptop (which i had re-arranged the keys to match Dvorak)
4) remote desktop becomes a pain. If you connect to your computer from another computer/keyboard, your computer will expect you to type Dvorak, but your keyboard will be in Qwerty.
5) No proven reports that Qwerty causes CTS (until computers came along, everyone was using Qwerty)
6) some of the laptop-keyboards don't have all keys of the same size. Also the holders beneath might not be at the same alignment. So re-arranging the keys might be a problem. This is more of an issue, if you use rented laptops, like in my company. On the next laptop-upgrade, they will replace your laptop and you will have to deal with the "re-arrangement of keys" issue again.
As a side note, i can say that typing English in Dvorak was more comfortable and natural, than Qwerty. But for the above reasons, i finally gave up.
