[Q]: I orderd this magazine in August... There should be some type of notation telling customers that it takes up to two months or more befoee the first issue will arrive.......What a waste of time. I could have gone to the library and received this magazine for free to read......I am still wating..... and there is no tracking number, therefore you just don't have a clear date for the arrival of the magazine.......not happy right now,,,,,,
[A]: Negative


[Q]: Bought this guy for a Mac PowerBook G4 Titanium (the description clearly states this power supply works for the PowerBook G4). Never worked. Couldn't say if this is a fluke or if they are all of comparable quality.

Negative
