Question: Change my Android device?

[Xi0N]

I Currently have a Samsung Galaxy Spica (Quite crappy if you ask me, but nice for the first android device i have)
I might have an opportunity to get a HTC Desire, but that would "chain" me to a mobile phone company for the next 18 months....
I know the improvement is quite nice.... but I know Desire has been in the market for some time already... so, my question is:
Is it worth to change to HTC desire, to not being able to change phone for another year and a half
OR
Better wait for a couple of months for some newer device, since HTC desire is quite "old" (Still better than Spica, definitely)

Well, more or less, what would your advice be?

Thank you!!

What are your other options? If you aren't planning to switch to any other phone than the Desire for the next 18 months, and the plan rate will be the same, I'd say go for it.

What im worried about is to get a phone that after some months willl be forgotten and not supported at all by HTC not by the community.....
My other options? If I want to get a phone given by a carrier at a low cost, this is the best I can get now.... but I cannot know which models they will have next month... (they change more or less every month or 2 months)....
