It's been four and a half years since I last bought a computer. Two quick questions for the experts: 1) I'll probably get a Dell Dimension 8250. Because the university I work for has a contract with Dell, I can get a decent discount. When is the best time to buy? Will there be post-Christmas deals worth waiting for, or should I buy now? 2) How are the current generation of DVD-R drives? Dell is now offering a "4x DVD+RW/+R Drive w/CD-RW including Roxio's Easy CD Creator" as an option. Should I get this or get both a 16x DVD and a 48x CD-RW? Thanks.
