Graduate student. Interested primarily in homotopy theory and the interactions of algebraic geometry with algebraic topology, but also in lots of other things, including Lie theory, mathematical physics, complex geometry, and graduating.

comment Properties of coefficients of ring spectra
For any space $X$, the composite $$MU \to KU \to F(X_+, KU)$$ gives with a complex–oriented $E_\infty$–ring spectrum whose formal group law is multiplicative. Feeding in, e.g., a Moore space for X will get you plenty of torsion. This isn't a killer example though, as these are augmented $KU$--algebras, and the augmentation cleanly separates the torsion from your other hypotheses. Still something you should disallow. // A recent result of Mathew, Naumann, and Noel (arXiv:1403.2023) gives some control over the behavior of torsion in $H_\infty$ settings. You may enjoy reading their main results.

comment Reconciling two viewpoints for spectra
I wrote some "nontechnical" notes that attempt to introduce the stable homotopy category by reasoning along the lines you mention. They have some deficits, but maybe you'll find they address your question: math.berkeley.edu/~ericp/teaching/Fall2013/msri/… .
