I have a 15" Crumpler sleeve originally purchased for a 15" PowerBook. The MBP Classic, which is 15.4", just barely fit in it. I don't think my new UMBP (ordered online) will fit. While screen size is the same, the UMBP is wider than the MBP Classic. Could anyone pls. comment how well the new 15" UMBP fits in 15.4" (Crumpler) sleeves originally designed before the new UMBPs or whether there will be a new size for new UMBPs?
