Let the hive mind of Engadget get that for you.
"I'm looking for a solid state drive, around 32 to 64GB, for use in my web server. The drive will contain my web sites and the operating system, either Windows Server 2008 R2 or Ubuntu. Large storage is handled by a separate RAID array, so capacity is not an issue. Rather, I am looking for the fastest, longest-lasting, and most reliable drive under $150 that is suitable to my application. Any thoughts? Thanks!"
"...the first-gen model lacks key goodness (3G radio, open platform, removeable battery..."
What would lead anyone to believe that future models will have a removable battery? iPods don't. The sealed case is one of Mac's core industrial design principles.
However, on an iPod, it's almost, *almost*, excusable but only because Apple tends to treat their customers well. After all, they did eventually replace everybody's battery after the iPod battery lawsuit and ensuing debacle. My concern is that because this is a cell phone, purchased through a carrier, I could see them being less inclined to do anything about it. If they leave it to Cingular, you're going to be S.O.L. if the battery fails. You'll be stuck with a device that cost you 4 large, locked into a two year contract, and some 3rd party company will want 120 bucks to replace a battery that costs about $6 to make.
