The latest gadget to hve created such a buzz that I know of is the iPad. But just like in any other gadgets, the first batch sold and distributed had problems that the following batches didn't have. Techies would often advice you to avoid such batches because this is often the case. It's just like a major pilot-testing going on.
Recently, the iPhone also got such flak and lucky are the ones with iphone warranty who can have their units replaced in one of the biggest gadget recall.
I know there's usually a rush to own the latest gadget but let others test them first. You may get bragging rights with your purchase but you also usually end up dealing with hassles that aren't worth it in the long run. Patience is a virtue with new gadgets, so remember that!
