Good bookshop, check inside the book before you buy. The thing about a book is it's always there, not just when some one may be around. I agree you can learn a lot on hear, but if you really want to learn get some good books, Such as "Bigelow's Troubleshooting Maintaining & Repairing PC's” Expensive but if you want to learn more than basics!!!!
All joking apart, I've purchased, and still do, every PC and Web mag available. But I've learnt more on here through two OS' than you can ever learn in print. If there is something that might come in handy in the future I add it to 'My Postings' by posting to the thread or 'copy and paste' it to a folder called PC fixes or whatever. HTH TR
