I'm NEW to Pentax, What should I expect?

Hello everyone;

I am new to Pentax and just switch from Minolta. I am not happy with what Sony is doing right now to I decide to get my first Pentax DSLR. My k20d will here in Two days from B&H fro $639.00 in total. Now tell me what should I expect from it. I really kinna like the K7 and its specs but I am not a rich person and thouhgt the K20d is best for my budget. I am however looking forward in getting some primes. Tell me reasons, in which I willbe compelled to stay with Pentax and I wanted to know some of your experience ( I meant not the spec) but what you like about it. Thanks
