"Won't be supported"... well, the product is being retired, I guess, but I trust Saitek's future software will be compatible with the X36.
As far as I could gather, the differences between the X45 and the X36 are:
- one less button (the "mouse" button of the X36 throttle)
- a differently shaped stick
- lighted buttons (big deal )
I also gathered that the software was changed with the X45. The new software isn't integrated with Internet Explorer, I heard (the previous software has sometimes been problematic because of that, according to some user groups). That software hasn't made available to X36 users yet.
Saitek may also have improved on the X36 design.
Note, however, that Saitek hasn't released any Win2k/XP compatible software. Neither the X36 software nor the X45 software will work with Windows 2000 or XP. Saitek has released drivers, but that means you can only program the joystick from the game, and some functions are not available.
For example, the X36 and X45 have rotary dials; they can be used as the axes they are (controlling rpm for example, or throttles) or can be used in "banded mode", in which you configure them to send a key when they're moved on way or the other. The banded mode is only available through the software. The same applies for the rudder rocker. That rocker can also be used in banded mode, if you already have rudder pedals, for example to control flaps.
You can't really use the mode and auxiliary switches without the Saitek software either.
But you can use the rest, yet without the software, only the main hat swith will act 8-way. The other hats will act like 4-way hats. (The 8-way capability for the other 3 hats is by software, not hardware).
Saitek Support told me by email that they should have Windows 2000/XP compatible software by the beginning of 2002. But rumors put the release in mid 2002.
And Saitek's track record isn't good. We've been promised Windows 2000 compatible software for Fall 2000, then January 2001, but we're still waiting for it a year later!
