Jacob, I wish it were that cheery. Do not forget the darker side of history. The prefix L- stands for levorotary. The levo comes from the Latin wording for left side. Left handedness is also known as sinistrality, from the Latin sinistra which also meant the left side, but over time took on

For anything other than the most intensive I/O operations, recent processors will give you very respectable performance. I don't encrypt whole drives but I do have some AES-encrypted disk images in Snow Leopard, and I get about 38 MB/sec throughput copying (using cp) and 60 MB/sec reading

Most non-structural users are familiar with the sequence of the proteins they are studying, and most software does at least display residue identity if you select an atom in a residue, so usually it is not necessary to do any cross checking besides selecting an atom in the residue and seeing

Personally I think it is a _good_ thing that those missing atoms are a pain, because it helps ensure you are aware of the problem. As somebody who is in the business of supplying non-structural people with models, and seeing how those models are sometimes (mis)interpreted, I think it's better
