Miss Chang, I'm not going to say much in response to your post for a couple of reasons...I don't want to get to off-topic, and, well, I just don't know where to begin, so I'll just say this: technology doesn't end, and if you want to miss out on technological advances that are going to save you time and energy while making your life more efficient and hell, healthier and longer as well, you are certainly free to do so. Hate blackberries? Don't buy one. It's pretty simple.
As for HD-DVD/bluray, I refuse to buy them as well. If others want them, fine. But the industry hasn't settled on a standard, which I don't like, and more importantly, even though I'm still willing to buy DVDs, I'm not going to upgrade to a newer, more expensive technology that really is obsolete already as well. If the studios had been smarter and not waited for peer-to-peer programs to corner the market, we'd all be downloading just about everything by now, and that's what we'll be doing in the years to come. And I'm really, really looking forward to that.
Man is a giddy thing, and this is my conclusion.
