First off: don't bump so much. OT has a neffing thread, if you want postcount. Your post is not going to get 'lost' anywhere by OT, in less than a day.
Assuming only Windows use...
Neither the N52te nor G13 are made for right hands. As of late, it seems these types of devices are getting used more and more by graphic design and CAD folk, that are either finding the keyboard/mouse too slow, or having RSI trouble with them for common repetitive tasks.
N52TE
Pros:
1. The wheel is very nice. I wish the G13 had one around where the 'left' joystick button is.
2. The flat stick is nice.
3. I find the square grid allows me to more easily get to all the buttons.
Cons:
1. The 'angry blue' (cheapo 'white' LEDs) backlight is annoying as all hell if the room is dark, IMO.
2. The hump of the hand rest requires you to have your hand pushed back to use it, which I can't see as being good for RSI.
G13
Pros:
1. The stick can be used a s a 4-way stick, analog stick (with poor centering--good enough for arcade style games, but not shooters or sims), 4 separate keys/macros, or as a titmouse.
2. There are way more buttons than the N52te.
3. Your hand can rest almost flat on it, making it comfy for long periods of use.
4. The base is nice, and not prone to moving.
5. The backlight can be adjusted by color and intensity, so it can be dim and not blue, if you want (I generally use dim reds, oranges, yellows, and purples).
6. The backlight color can change by profile/mode (each profile has up to three modes, accessed by the buttons above the keypad), so you if you use multiple modes for one game (or real productivity application), you can get feedback as to if you switched correctly by using your peripheral vision.
7. The software allows for highly flexible scripting, via Lua. It takes a little effort to more than basic macros with it, but it's awesome (and, most basic macros can be recorded in the software).
8. If you set up your keys and buttons accordingly, you can augment the software's functionality with other key/button software, such as autohotkey, xpadder, or joytomouse3.
9. If you have multiple computers you use it on, you can save your profiles to the device, so that if you adjust them, those changes stick. Not useful to me, but I can see it coming in handy, for actual professional users, taking their work home.
Cons:
1. If you don't have long fingers, you will have to give up a row of keys. At this point, some previously-gibberish user reviews will start to make sense. Also, you'll get why people pay a decent bit used Saitek ones on eBay.
2. The key layout makes it hard to reach some keys, even though your fingers are right over them.
OTOH, While I can't use several keys, due to 1 and 2, I can still easily access more keys than are on the N52te. So, even if you have smaller hands, it's quite nice.
3. IME, the profile-switching software doesn't work right. It will automatically switch upon app start, but changing focus, it never switches back. What I did was enabled manual profile switching from the pad. Personally, I would like to have a force profile menu in the tray app.
4. Scripting can be time consuming. It's not hard (assuming you have some programming experience), but i takes a little time to get used to how they planned for it to be used.
5. You need plenty of desk space for it.
6. Very minor: they could have easily adjusted how the color setting works in the uC, such that the color palette actually give you an approximation of the color you'll see.
7. Personally, I find the device useless for games that have controls properly designed around WASD, and that are fairly customizable.
Note: if using Vista or 7, and using it for normal Windows GUI apps, you may find it not working in some of them, even with a forced profile. The solution is to make the software run as Administrator, and deal with the UAC prompt.
