Well 325 bucks for new Mean Machine, that's cheapest chips...right. Go for N900 - don't even ask if is it still under development - it is big time man. If You are used to your device, and You enjoy at least it's half of potential (as You wrote that You are't big fan of command line) You will be (for sure) bored with any other phone/tablet/what ever whitin couple weeks. May advice to You is N900, so You can enjoy and discover more and more things every day.
