Slates do have advantages when working in certain circumstances, but I'd say those applications-of-use are few and far between. After looking at the details and specs I said to myself "OK, where do I use an iPad where a smartphone/netbook combo would kick me to the curb?" I'm still looking for the answer.
The truth is $600 gets you a smartphone AND netbook that beats the iPad for both productivity and portability. $130 for a 3G chip that costs maybe $30? RIPOFF!
As for the lack of flash support, that's now become a double-edged sword in my opinion. While it does make netbooks superior to the iPad for surfing, it's high time somebody gave Adobe a wake-up call! Rather than bash Apple, Adobe's suits should focus on reworking their resource hog, especially if HTML5 succeeds in cannibalizing flash content.
