I do have several issues with the EP121. Let me list them out:
- The connectivity of the bluetooth keyboard is occasionally bad. I usually use keyboard shortcuts on Photoshop for many things, and sometimes the keyboard would stop working completely. When this happens, putting it to sleep and waking it back up often works. Sometimes it doesn’t, though, and that’s when you have to restart the tablet.
- The EP121 comes with Windows Home Premium, which does not give you access to turn off that “ripple” effect that Windows 7 makes when you tap on screen with the stylus. The ripple doesn’t bother me, really, but because Windows creates that ripple, there is a split-second delay on Photoshop when drawing, and so your lines come out crooked. It’s extra work, but yes this can be fixed. There are tutorials all over the net from other users who are equally irritated by this ripple effect. If you don’t mind shelling out another 100-200 bucks, get the B121 instead, because it comes with Windows 7 Pro, which gives you access to turn off this ripple effect.
- Screen rotation is retarded. When you rotate the tablet, the screen is supposed to rotate, but sometimes it doesn’t. When that happens, you have to rotate it, hold it in that orientation, then restart the Windows. I always use my tablet in landscape orientation, so it doesn’t really bother me.
- Calibration issues near the edge of the screen. I thought this is just the defect of a tablet PC, but several people who own a Cintiq have told me of a similar issue with the Cintiq. Basically what happens is that when the cursor gets near the edge of the screen (about 1/4” to 1/2” inch from the edge), the cursor starts shifting away from the tip of the pen. But seeing how I don’t draw anywhere near the edge of the screen and I can simply move the window away from the edge, I don’t see this as a problem.
- The 4GB of RAM is kinda too little for me. When I work on a large canvas at 300 dpi, large brushes start to lag. But if I’m only doing sketches and storyboards (which is what I use it for, mostly), there’s never any problem.
That said, I feel the EP121 is a great little tablet PC. Of course nothing beats the 2048 pressure levels of a Cintiq, but this one does what I need it to, and it allows me to work outside. I find myself increasingly unable to work inside my room, so I’d choose the EP121 over a Cintiq any day.
