I'll get flamed for this. But here is some honest truth about iPads...
Using an iPad is like going backwards in time some twenty years! You can't send attachments in the iPad's native email app.... Forget multiple attchs, you can't even send one! If you don't own one you won't believe that, bit it is true! The email app is junk. And it would be easy to write any number of email programs that would be better, but of course, Apple does not allow that!
More proof that the iPad is a time machine that only goes backwards? When was the last time you used a computer that didn't have undo? Can you imagine using a device for more than ten minutes that didn't have undo? Well, buy an iPad and you can experience that for yourself... Again... After all these years.
Unreliable, browser too. Although this is supposed to be one of the iPad's strengths... It really isn't! Going to websites with iPad Safari is worse than twenty years ago. At least back then when you went to a site, if you could load it, it worked. With the iPad you never know if a site is going to work or not. I just got dinged $15 by my credit card company for missing a payment that I had made at their site using... You guessed it... The iPad. The payment appeared to go through, but as with many sites using forms, you just never know if the site has properly processed inputs from an iPad. In my case, the payment appeared to go through, but actually didn't at all. Fun, eh?
And wait until you try to type on one! My Palm Treo had better predictive typing. You must constantly correct the iPad's lame suggestions that are used by default, while you type. Depending on what line of business you are in, the iPad will make you sound like you are just a clumsy typist, or completely illiterate! And then trying to position your cursor in a TYPING FIELD LIKE THIS ONE is a complete nightmare... It is slow, if it works at all.
I'm pretty tech savvy and have tried to make my iPad useful for nearly ten months. My netbook is way more useful, day-to-day. I travel extensively and had originally hoped to replace the netbook with the iPad... Today, I just laugh at how naive I was! It is the iPad that I don't bother to pack, now!
