Remember, the same thing happened with the iPod Touch, Apple's iPhone-based PDA. The first-generation iPod Touch could play only a few sounds and even then only at a whisper, so its calendar alarms and new-email alerts were useless unless you wearing its earphones. You couldn't change the volume without using the touchscreen - a real issue when driving, jogging, or carrying groceries. There was no microphone, so you couldn't take voice memos or use services like Skype. (Apple even blocked external microphones from working on it!) Despite Apple making sure each iPhone OS revision has continued to support the first-generation iPod Touch, those hardware limits remain in the actual devices. You can bet that similar types of issue will be discovered in the first iPad.
