I'm looking for laptop bag suggestions, ideas, and recommendations.  I currently have a great bag - it's an Ogio (I forget the model), but it's the best and most spacious bag I've ever had.  That said, however, I am in the market for something else.  I travel quite frequently and my bag weighs in excess of 50 lbs and my back is taking the toll - not to mention that it's a pain at airports.

Here's what I need in a bag:

• Must be able to have as a carry-on on a plane.
• Must be able to carry a Dell Precision M90 (17“ monitor) + accessories
• Must be able to carry a Dell Inspiron 8600 (15.4“ monitor) + accessories
• Must be wheeled - I don't want to carry it all the time.
• Have more room to carry 1+ external hard drives, headphones (Bose QuietComfort 2), power strip, etc
• Preferrably have more room for a few magazines, a book or two, papers, notebooks, etc.

Any suggestions?

I'm considering the following:

• BulkHead PRO 4:1
• Spire Meta (but I'm not sure if it'll hold two laptops + gear)

I've seen others but they're less than inspiring.  I'm hoping that people have some good suggestions 'cause I'm at a loss but I need to get one soon.
