It's no surprise to see the K53E win in nearly every benchmark. But the Eee Slate excels in the storage test thanks to its 64 GB SSD. The only aberration is the Importing Pictures metric, where the K53E beats the Eee Slate.

The Eee Slate does poorly in this test because its SSD chronically suffers from poor random write performance. Normally, this is where SSDs utterly trash their magnetic predecessors, but Asus chose the SanDisk SSD P4, which seems to be an exception. No doubt, this is a situation where "my HDD is faster than your SSD."

Perhaps Asus should have chosen a better SSD. Even our older Seagate Momentus 5400.6 beats the SSD P4, with random 4 KB writes as low as 200 IOPS (.77 MB/s), while the current Momentus XT hits 338 IOPS (1.32 MB/s).

    Looks good but IMO,Win7 isn't designed for touch screens.Hopefully Win8 will add a decent touch UI to the OS which makes the Windows tablets more useful

  • I think thats the worst idea in tablet world; putting windows 7 on a tablet... dealing with sidebars even makes me sick on 24" screen with a hi-res mouse... I cant think of it on 12" screen with fingers... and thats already tried and failed a few years ago; tablet PC's... Will somebody take any lesson from failed ideas? or even from Ipad's success? Grow-up and see what's happening... or leave it all to Apple...

    All this tells me is that the inevitable rise of Fusion or Sandybridge with integrated graphics, or ION based tablets, Windows 8 will steal the show.

    When the hardware gets to a good enough standard then the peoiple will flock to a REAL operating system.

    I'd like a W8 tablet that could simply change interfaces between the WP7-esque look in tablet mode and a W7-like interface with the addition of a keyboard dock (basically a W8 Transformer).

  • I current own a ASUS slate. For those who are interested in this tablet. Here is my suggestion. Get the 2G ram/32G SDD one. and upgrade the ram to 4G and intel X310 series 80G. the final price will be abour $50 more than 4G/64G one; however, u gain better SSD performace as well as more storage. I have been using this one for 3 monthes now, I would say, compare to wacom's other drawing table, this one still a little beyond, however, when u compare with Wacom's Cintiq12WX, Slate does provide the same function, without an extra computer. I would say 256 level vs 1024 level is a little trade off for convenience and price. As a graphic designer (not illustrator), i dont really find the 256 level is a huge issue. Tho if ASUS intend to relseae 2nd Gen of this product' i will be really interested in seeing them switch to AMD fusion. intel's HD chip is simply a joke. I would trade off some CPU power for more powerful graphic. Anyway, final thought.. this is the only table with pen function that can run Adobe CS5. I only hope it wont be hard to find the replacement battery...

    A tablet with Intel graphics and Windows OS? What a waste.
