Good reasons for switching to Familiar...

I did a quick search with Google and within this forum but didn't find what I was looking for...
I have an ipaq 2215 with a xscale 400mhz cpu and 64 megs of ram. What I'm wondering is why I should switch over to Familiar.
Will it run faster?
Is there a lot more functionality? Things I never knew I needed...
Will it allow me to use landscape mode even though it didn't come with that functionality?

2003se seems to be serving my needs quite well as it is but if there is a mountain of functionality I'm missing out on that can be found in Familiar I would really like to know. Thanks allot for your info...
