I thought I would be able to use the ipad for very simple database entry (benchmarks while testing) but even for that it is much better to use a laptop.
If you do "banking on the go" and "checking data at work" and stuff that you really don't need to be portable, these are just more examples of it being a toy. You are just coming up with things you CAN do with it. Not that there's anything wrong with that - sometimes toys are for 'work' too. That doesn't mean it's not still a toy
