The Galaxy Note 10.1 looks to be a really promising tablet with its unique pen input. Samsung has been continuing to make revisions on the hardware/design and this has caused delays. The changes have been mainly the CPU upgrade and the new slot for the S-pen. If we had to guess we think it would be available near the middle of the summer. We will update the release date as we get more concrete information.
Samsung has decided to lose the 1.2GHz dual core Exynos processor initially selected to power the tablet, and go with the 1.5GHz quad-core Exynos 4412 processor.
