Note that it takes a couple of days to realize the advantages and get a feel for it, so a simple trial of a few minutes might not be long enough to sell a person on the HHKB Pro 2.
That's pretty much the case with all quality keyboards. If all you have ever typed on is a cheap keyboard and you are used to spending $10 bucks for them any quality keyboard is hard to justify. But once you use one for a few days then go back to that cheap board your fingers will let you know immediately why good keyboards cost considerably more than that cheap board.
Where it really gets hard though is when you get a keyboard with good switches (Cherry, BS, Alps ect..) justifying moving up to the topre based boards is really hard. I mean lets face it topre based boards are expensive ( about 3x ) and that is hard to justify if you are farily happy with what you have.
What really pushed me over the edge is that most of those that do take the chance and get one love them. True there are some that don't like them for what ever reason. But they are by far the minority. Also start taking a look at peoples signature. What you will note is that those that have them generally have more than one. And if they do only have one they want another one. After making those observations I decided to take the plunge and got the 87U and if you take a look at my signature you will note that I have already acquired another one (86U). Not only do I not regret paying 350+ for the 87U I'm more than willing to pay it again to get another one (Luckily for me I won't have to pay quite that much for the next one though).
Any ways I'm a very happy owner of two topre based boards and can't help but express how much I love them. Besides as has been said before if you are one of the minority and don't like them you can sale it here with out much problem. If it is a HHKB pro I may be the buyer
Or for that matter any of the topre based board.
