I bought the Purple Houndstooth/Black wheeled carry-on for my wife for her job because she sometimes works 2-3 (24 hour) days in row at her Home Health Care business.  She really liked it so what more can I ask for?  A little overpriced but I do like the High Sierra luggage that I have.  I don't use mine as a carry-on because you are pushing the size limits on most airlines (especially when you load it up).  Lots of pockets and compartment separators for convenience.
