I've been using the K810 [1] for some time for all my computers. I find it absolutely brilliant to type on (being mostly in vim, the awkward home/end, page up/down, arrows etc don't matter very much), and it also has the ability to switch between 3 paired bluetooth devices. There is also the Lenovo Thinkpad Compact Bluetooth [2], which I haven't tried, but allegedly "features a simplified pairing with the system through Near Field Communication (NFC) tag. Simply tap and pair with an NFC-enabled system." It also has a TrackPoint nipple. Of course, neither of these have the slot for phones/tablets.

The K810 is quite a nice keyboard, IMO better than the Apple bluetooth keyboard in terms of feel. It appears to be functionally identical to this new K480 and would appear to have the exact same physical keyboard.

additionally the K810 is backlit, which this does not appear to be, the backlit function is fantastic.

Really surprised it is not backlit, it seems like all the other keyboard options are.

Coming from a keyboard geek, their TK820 is by far the nicest keyboard they do in terms of actual keys and switches and the trackpad. It isn't backlit though, that's the only box it doesn't tick. I've got a K830 for the livingroom and it's nowhere near as good.

I know this is maybe nichey for certain people but lack of a print screen key on the TK820 is an issue for me. I loved it otherwise. Just got the 810 spoken of above and despite being a smaller unit, has the printscrn key.

The K480 is listed as half the price of the K810.

Touch typing skill is worth at least 50 bucks, apparently :)

yup, just picked up a k810, quite hapyy with it for my surface pro 3. Added my android phone as a 2nd device to pair to. Key strokes are good, connection has been very reliable, no latency. The apple keyboards have this bodily twang when typing on it (it cheapens the feel) that the k10 thankfully does not have. it feels more solid. I can't say it's the perfect keyboard, but it's great, worth the price. I even overpayed at my local big box store and I don't mind that much.

Of course, there are quite a few stands for a mobile device, so this shouldn't be a problem. I am not sure I would want to have the "monitor" so close to my eyes anyway...

I'm not sure how close you're imaging sitting to it, but it's about as close to you as a laptop display would be.

Yes - that's too close for me, at least for daily usage.

The only gripe I have with using bluetooth keyboards for my desktop is that batteries seem to drain much faster than the models using proprietary dongles.

What is your experience with the K810 ?

This is why I love my K750 with integrated solar panels. No batteries to worry about; it just works, always. And it's great to type on.

I tried the K750 and found the keys spaced out wider than I was used to. Did you get used to it?

I switch between a Macbook Pro and a Windows ultrabook (long story) and the keys are spaced slightly different on both. After couple days of finger-confusion, my hands just adjust to them easily. The mind/body is amazing that way.

I've got K760 (Mac one) and it's simply amazing. I think it's died on me once (when it didn't get enough indoor lighting) in like 1.5 years.

I've been using this K750 with the solar panels for a while now... no issues whatsoever.

The battery time is probably my biggest gripe with it as well. I keep the backlight continuously on at the lowest setting (it turns off when inactive), and I think I get around 3-4 days of heavy usage (note: ballpark estimate!). The battery is also not (easily) replaceable. So while it's no problem from day to day (and you could keep the USB cable connected at all times if you wanted too), it's quite poor compared to regular wireless keyboards. The USB cable is only for charging btw, so I've played with the thought of gluing one of those superthin Qi pads to the back of the keyboard :)

Yikes, that' abysmal. I have an iMac and use the apple wireless keyboard that comes with it and I can't even remember the last time I changed the batteries.

I may be mistaken about the battery time, so don't take my word for it. The Logitech site says about 10 days with backlight on (12 months(!) without it)[1]. And while I get the Ubuntu keyboard battery warning after 3-4 days, there still may be a few days left in it.

It's worth noting that the K810 is rechargeable, however. You can leave it plugged in over USB while it's at your desk, and unplug as needed. I carry mine around with a tablet as a laptop replacement and charge both every few days. I can handle 2 or 3 days of life if it means I don't need to stock AA batteries.

Yes, actually I like the idea of an internal chargeable battery through USB much more than replaceable AA batteries, since nowadays I´m very likely to have one (or two) USB chargers around when I´m travelling.

I'm really glad you pointed out the lenovo, that might be just the media center keyboard I've been looking for.

What are the physical dimensions of K810? It is strange that Logitech does not specify them as it did for K480.

Logitech specifies them, just scroll down

Height 20 mm (0.79 inches) Width 299 mm (11.77 inches) Depth 195 mm (7.68 inches) Weight 820 g (1.81 pounds)

The K810 requires a touch more to track down, but: Width 287 mm (11.30 inch) Depth/Length 127 mm (5.0 inch) Height 5 - 10 mm (0.20 - 0.39 inch) Weight 337 g (11.89 ounce)

The only con to the K810 is it does not incline.
