So much hypocrisy in this forum... No, Apple is not going after Samsung just because of the round corners. There are many other tablets with round corners, after which Apple is not going, for some reason. I can't remember ever going to a nearby BestBuy store and thinking "wow, this iPad looks weird..." about something that upon closer inspection turns out to NOT be iPad, until I saw the Galaxy 10.1. Only a blind person will argue that it's not "inspired" to a very high degree by iPad. And if you consider other things Samsung has done (a Galaxy phone power adapter being nearly 100% identical copy of Apple's iPhone adapter, using Apple App Store and Safari icons in its brick and mortar stores being the latest publicized examples) - it does make one wonder what's going on here.
As far as the tablet designs are concerned, isn't that curious that only after the iPad came out all these "there's no other way to make a tablet" arguments begun? Of course there's isn't, now that Apple has shown it! It's how it's always been: right as soon as someone comes up with a brilliant idea - "it's so obvious!" - and yet, nobody came up with that obvious idea before. Curious, isn't it? Yet, Microsoft had some interesting ideas about a tablet design that's nowhere near iPad's (which never realized, I might add). Their recently shown Mango UI is completely different from iPad's. It's weird for me to say so, but Microsoft really did innovate there, instead of going the easy way, as Samsung did.
HP's Touchpad and RIM's Playbook are two other examples - both different from iPad. Both had great potential, but lacked the polish that Apple has put in their iPad and iOS. They both failed, but not because they were bad - they failed because the companies that made them were being lazy.
I love my iPad. But I also LOVED both the Playbook and the Touchpad, and was considering buying one of them (although couldn't quite make my mind up which one :) ). I was leaning more towards the Playbook, being somewhat familiar with the QNX, but it's lack of an email client was a deal breaker for me (as well as pretty poor developer support). And that's one of the reasons it's failing. And HP's decision to abandon the Touchpad was a bummer as well. So both of them failed because of one or another stupid decisions made by the companies that produced them. And neither of them were imilar to the iPad to a degree to which Samsung's Galaxy Tab is.
So we now have at least _three_ different tablet approaches, clearly indicating it's not just about the "round corners". Two of them failed for reasons NOT related much to how they look or work. Another may or may not succeed. And then we have Samsung Galaxy Tab. Not a bad tablet, mind you - in fact the best Android tablet (and I wanna say "the only one worth looking at") by any means. But a copycat nonetheless.
