With the release of 2.0, I would think now would be the time to buy an iPod touch if you were in the market. But, as I watch the Buyer's Guide, I find out that now is in fact not a good time to buy. Why not? I've been waiting for a while (saving up) and am really looking forward to buying. Is this "don't buy now" advice just telling us that an update is coming in September (maybe)? I don't want to wait if I don't have to. Advice??
