what is the difference between the p4400 and the p4460?

This device, the P4400, will reset all of its timed measurement values to zero if power is lost or the device is unplugged. The P4460 has "non volatile" memory, using a battery to provide the necessary voltage to power the (S)RAM memory, which means that it will not lose the data if power to the 4460 is lost. The P4460 also will let you input the cost per KWH from your provider to calculate the cost to operate the appliance over a week, month and year (assuming that your use is the same during the extrapolated period as it was during the measurement period). For me the data retention feature is well worth the extra $4 since I want to keep track of the energy used by a window air conditioner which will vary by the outdoor temperature, the sun hitting the building, the humidity, etc.

I can not find any difference. I can only assume that the 0865 replaces the 0855

The PRS-300 and the PRS-600 are both newer models. The 505 preceded the 700. The PRS-700 was originally intended as a successor for the PRS-505 (it's faster - and has that input capability that a touchscreen gives you). The PRS-505 in turn was the replacement for the PRS-500. However, the 700 (despite being in many ways quite similar to the 505) had certain specific flaws (and a couple of benefits). It, unlike the 505, has a touchscreen, and it also has a light embedded underneath the touchscreen and above the eInk screen. On the plus side that means you can read in darker places without carting a little light around with you, but on the down side it and the touchscreen combined made for a screen that wasn't quite as readable as the 505. In short, yes, basically the 700 has been replaced by the PRS-600, which is pretty similar with slightly better readability, I think also a dictionary, but no embedded light. The PRS-300 is a smaller, cheaper, but otherwise very familiar touchscreen-less PRS-505ish device, except that it contains no expansion slots, and is therefore not terribly useful if you're the sort of person who wants to carry the entire Project Gutenberg in your pocket ;) Speaking for myself I'm pretty happy with both the PRS-700 and the PRS-600 models, despite the somewhat diminished readability - I have never owned a 505 so can't comment except to say that I've seen the screens on them and they are astonishingly clear and paper-like. I would probably buy a PRS-300 if I had the cash and it had a memory expansion slot! Hope that helps...

I believe the main difference is that the 40160 comes with two sets of brushes. One for hardwood and laminate floors, and one for tile and grout. The color of the unit is different also. Other than that, I don't think there is any difference.

Same. They are usually neck-and-neck, with the P7000 leaning more towards DSLR owners, and the G12 more towards point-and-shooters. However, since Amazon is selling the P7000 for ~$240 right now, there's no contest.

I'm not sure since I didn't get to see a comparison between the two when I went to Best Buy, but I found out that the PN42B400 model has the same E-panel technology (wide enhancer 2, .001ms response, 600Hz subfield motion, mega dynamic contrast ratio) as PN42B450's, except for the Filterbright antiglare feature. For me, it didn't justify paying an extra $124 just for Filterbright and a few extra ports. Hope that helps!

From the pictures, it looks like the 'P' version would come with a few extra attachments. I think the other answers here would not be able to tell you the difference unless they specifically ordered both.

To be honest I don't see any difference. We purchased the 20632 and my husband loves it.

I am sorry, I do not know the difference between the N4010 and N4110. You will need to contact the seller for this information.

I'm sure this is too late for the OP, but wanted to chime in if I may. From what I found/feel, the PA249Q is the true successor of the PA246Q. The most notable difference is that the 248 is not wide gamut, nor 10-bit capable. I'm sure the 248 is nice, as about everything from ASUS is. However to many professionals, this is likely a deal breaker.

I have the 3220, and it's fine. Black is black. I never bought the color, so I don't know about it.

I do not know what is the difference between the two. Maybe one is a older verison (AQ-4000)? Hopefully, someone else can answer the question for you and me. ;-)

the r7000 has a faster processor in it and a faster connection at the 2.4GHz range (up to 600Mbps compared with up to 450Mbps on the r6300). Other than that it's seems very similar. with a hard drive connected you can have computors/laptops etc. auto backup your music, pics and vids, files, and even a restoration in case your device crashes. The saved files can be accesed by any device connected to the network.

I really don't now the differents between the two. I read about the model #52244only and bought it. Sorry Iccan't help you.

The hardware is identical. The 6471 comes with windows 8 and the 6860 has windows 7

Edit: Sorry for misleading, they are both ficker free. The major difference is GL2760H is TN panel; GW2760HS is VA panel. And GW2760HS has 1W*2 built-in speakers; GL2760H not. Another difference is GW2760HS uses a DC (Direct Current) method for background light brightness control but GL2760H use old PWM background light brightness control. In another word, GW2760HS is flicker free but GL2760H not; that's why GW2760HS more expensive.
