Is this "old model" worth getting, or should I consider C5-03, C6-00, X6 8GB etc?

Is 5530 one of Nokia's earliest touch phones?

I am concerned that it may have other serious flaws (like the ones I hear for N97 mini, N97, C6-00, and C7).

I needed WLAN, so I don't mind not having 3G or GPS.

What is the price now?

I understand that 5800 came first, then 5530, and now the Cs (and of course there's the N series and E series touchscreens).

My concern is whether or not the 5800 or 5530 would be good for me, being older phones, than a newer C5-03.
