The only drawback is that you void your warranty if you try to do this, but if your iPod is under warranty you can have the battery replaced for free anyway. If you want to have Apple replace an out-of-warranty battery, the charge is $99. That includes the battery ($49), the labor cost (probably in the ballpark of $20), overhead, management, and paying for everybody else that touches your iPod when it's in repair from the guy working at the loading dock when it comes in to the person that hands it over to the shipping company on the way back. $99 is NOT unreasonable. A removable battery would be nice, but the iPod would be neither as small nor as good-looking as it is now.
2. There is NOTHING Apple can do about the longevity of the batteries. Lithium ion batteries have a longevity of about five hundred charge cycles. If you use the battery until it's dead and recharge it every day, those five hundred cycles will be depleted in about seventeen months. This is NOT a gaffe on Apple's part, it's just the way lithium ion batteries are.
