which DSLR - Canon EOS500D v Nikon D90

Hello experts,

I'm looking for my first DSLR.. finally getting out of the shell.. although I personally feel nothing like a slim (and powerful) P&S.

Although my first one, I want something which wont get out dated in a couple of years !
I have shortlisted to Nikon D90 and Canon EOS500 but still very open to other suggestions.

I'll mainly be using it for holiday pics may be family occasions/functions.. etc.
But I do want the one which could take HD videos. (also are there other cheaper models by Canon / Nikon which may be better value for money?)

What do people suggest, personally I think very highly of Nikon as a brand, but have heard that off-lately canon is making the best DSLRs.
also what are peoples' thoughts on other makes like Pentax, Panasonic, Sony, Olympus and others? I did notice some of these with pretty high review rating on the website?

Any suggestions would be greatly appreciated.


Cheers
