I have all of these. If price was not an issue i would rate them in this order from best to worst. Xoom, best feel, best all around quality,screen is beautiful, resolution is fantastic, camera is the best, video quality is the best of all of them, battery is on par with the playbook about 9 to 10 hours, size if great, the speed might be a tad slower than the Acer or the transformer, but its not easily noticeable, button placement is great. Whats not so great is my computer didnt easily recognize it, and the user interface to transfer pictures from my computer to the xoom WAS NOT EASY. But if price was not a factor, the Xoom would be my first choice. btw, all cords with this are just perfect nice length and quality. Asus Transformer, If price is an issue, than this is the one to get, ( if you can wait, lol. since its right now been on backorder twice, i lucked out and got mine at Best Buy during the day before it was sold out again.) Build quality is second to the Xoom, the screen is great but the Xoom edges it out just a tad, i think its a tad faster than the Xoom in browsing speed, the battery probably will last about the 7 to 8 hours as it says, size is great, good feel, all cords way to short, the cord and plug, or in laymans terms the brick gets pretty warm and from what i hear heat and electronics is not a good combo. When you plug in the adapter to the bottom of the transformer it feels kinda cheap, and i could pull it out rather easily. This is a very good contender to the Xoom, Asus from what i understand makes its own parts for this. Let me add that this is much lighter or atleast has a lighter feel than the Xoom, and also that the Xoom is two hundred more than the transformer and as you can expect for two hundred less you get less, but i dont think two hundred less, perhaps in parts, but not in what it offers. one more thing, the video quality is definetely not as good as the Xoom, the Xoom's video quality is right up there next to the Playbook, which is excellent, when you hand the Xoom to someone and let them watch a video you took its like you were there watching it. lol, one more thing this offeres that the others dont is a pre installed app. called my cloud, AWESOME!!!!!!!!!! lets you control your desktop or laptop remotely from your transformer, ideal for all you day traders out there like myself needing some time away from your desk for awhile while still keeping an eye on positions. Acer A500, physically bigger than the transformer, definetely more plastic which comes with more plastically feel, just as fast as the xoom, or transformer, you wont notice the difference in either of these. has full size usb, but who cares lol, screen is not as nice as the transformer or xoom, battery from what i hear is just as good as the transformer, but not as good as the playbook or Xoom. Camera and video quality is not as good as the transformer, needless to say not even close to the Xoom and playbook. Blackberry Playbook, if this was a 10 inch model it would be my favorite, size kills it. multi-tasking is excellent as everyone says, video quality, screen quality, screen feel, user interface, battery life all are the best, along with its five hundred dollar price tag comes high quality. so far it is the most expensive 7 inch tablet, and it is worth it. if you want a 7inch tablet, price will be the only thing you will be able to complain about after you use this for awhile. The feel is perfect, speed is not as fast as the transformer, or the xoom, or the A500 but faster than the galaxy, dont get me wrong its not slow, just not as fast. Samsung Galaxy, good tablet, screen is fine, play back videos is ok, battery like fine, browswing speed is ok, its nice, nothing to write home about. Dell Streak this is the fastest one bar none atleast of the ones i compared. picture quality is not so good id rate it a 3 or 4, video quality is not so good same rate a 3 or 4. it feels like a toy, looks like a toy, user interface is ok, the only standout is the raw speed, and that it excells at, if you wanna browse from page to page quickly than this is the one for you. but so far thats all its got. one more thing, battery life is 3 to 4 i think. Acer W500, SEND THIS THING BACK, slower than slow, basically a small laptop except for if you lift up the back plate you can see a mouse on a wheel. This thing has the newest AMD processor, and on this windows tablet, AND IT IS TERRIBLE. I have read that Windows is not user friendly on tablets, THIS ONE TIME YOU SHOULD PAY ATTENTION TO WHAT OTHERS SAY, if you want to browse the internet on a tablet, PLAY UTUBE VIDEOS THAN DO NOT GET A WINDOWS OPERATING SYSTEM TABLET. you will not be browsing happily. It seems like a good idea, but it is not.. Android or blackberry operating systems are the only way to go so far to browse on a tablet. hope this helps in your selection
