Perhaps we're not the target audience...
The most interesting take I heard was from a commentator that suggested that it was a killer device for the less computer savvy contingent.
The tablet would have a closed OS with no need for Antivirus protection, automatic updates, easy to purchase content and a relatively intuitive operation with a netbook-like price.
In other words, it's perfect for my dad. It could be his primary computer for email, web browsing, reading etc and not cause me nearly as much computer support stress.
I wanted the tablet that exists in ST:TNG that is super thin, tough and magical. This isn't it but perhaps it's the first step. I'm not an early adopter so I'm willing to give them some time.
BTW, many of the other "issues" such as Flash support can be remedied by a software update. Software limitations are annoying but can be remedied (see cut & paste on iphone), only hardware limitations are worth getting worked up about.
I wonder if some of these launch deficiencies such as Flash will be gone when you can actually purchase it.
