Q: I was installing these chips in a G4 Sawtooth macintosh computer and the chips did not work. I had kernel panics that eventually left the operating system unusable. The hard drive had to be reformatted and the OS re-installed. A great headache and PITA. I need to return these memory modules, how would I do that.best regards,vilppu

Q: I was enchanted with this fascinating book on barn conversions. Barns are great relics from our past, conveying a sense of history, but many have been ruined by weather, time, and neglect. I didn't realize how many creative architects and owners have made barns useful for both residential and commercial use through renovation and restoration. The intrinsic character of these old barns brings an integrity and charm rarely seen in new construction. In many gorgeous illustrations, Rooney describes the history of barns, their adornment (who knew that it was all because of a 9th century pope that there are so many roosters on weathervanes?), and their use as gorgeous residences and fascinating commercial and establishments - including an architectural office, inns, and even a funeral chapel. One entrepreneur even used several to develop an office complex. If you love barns and if you like to see the past preserved in the present, you will love this book.

A: Positive

Q: True, it is more expensive than non-Canon caps, but after all you are using it a hundred times on a photography day and it works the best (I have a $5 non-Canon one and every time I had to use it it felt cheap and flimsy). Just another small thing to enjoy your shooting more.One star off, as it still could be 30% cheaper.

Positive
