So, just to comment on the disk reads: the local, non-persistent disks don't offer great speeds (you're right). However, that shouldn't matter too much now. All of your application code should fit in memory once it's been read off the disk and so you shouldn't be hitting the local disks much after boot. Static files should be on S3 and databases should be stored on EBS.
EBS has great performance. RightScale noted that they got over 70MB/s with sysbench and over 1000 I/O operations per second. If you want more performance, you can even stripe across EBS volumes.
EBS really helped EC2's viability a ton. EC2 users now have access to cheap, reliable, and fast storage.
