Samsung, Barnes & Noble Drop Tablet Price. Worth It?

Last week Samsung announced the Galexy Tab 2 student edition for $250. While it is the same price as the regular Galexy Tab 2, the dual core tablet also comes with a bluetooth keyboard and adaptor to allow use of usb drives with the tablet.
Further more, Barnes & Noble announced a price drop in their Nook color and Nook Tablets. Nook Color is $149, Nook Tablet (8GB) $179, and Nook Tablet (16GB) $199. Essentially a $50 drop in price. This was done to compete with the Nexus 7 by ASUS.
This begs the question of whether it is worth it to get either one of the tablet options over the Nexus 7? With respects to the deal I can honestly recommend the Nexus 7. While the peripherals for the Galexy Tab 2 is great and while the Nook devices have expandable memory, both are running processors that are dual core (or in the case of Nook Color a 800mhz single core processor. Also both are running old software and lower screen resolution. Over all the fact that the pricing is fairly comperable to the Nexus 7 pricing there is just nomajor reason except the expandable memory not to go with the Nexus 7. Even with that the use of services such as Google Drive, Box and Dropbox (among others) solves any major storage concerns. I have a 16gb Nexus 7 and memory isn't such a big deal. If your iching to get a 7 inch tablet, the Nexus 7 is a far better deal with more flexability as well.
