Pros: Small size, light weight make this keyboard easy to put aside when you want more desk space for other work (e.g. eating sandwiches).
Cons: This keyboard uses a single rocker-key in place of the 4 conventional arrow keys. This makes use of the the keyboard impracticable for gaming, but it also makes it hard to use the keyboard with any application where you might new to use the arrow keys, wh
Excerpt: I purchased the Microsoft Arc Keyboard in white because I needed a keyboard that was wireless, compact( I don't have alot of room where my keyboard sits) and functional. I also loved the white color(very clean looking). I was very happy with it, it was comfortable, easy to use and fit perfectly in the space but within a month it stopped working. I have no idea why, I replaced the batteries thinking that may be the problem but it still didn't work.
Summary: Bought this with a wireless mouse to lose some clutter from my work station , leads and wires etc. Some times found them to be slow and unresponsive , possibly due to the amount of other wireless traffic , iPads iPod , printers , laptops in the area , eventually lost the will to live and reverted to wired. Having said that they are beautifully made!
Summary: It's hard to get excited about this product as it is only a keyboard. I only got this one because I was pushed for space on my desk. I would have preferred a larger one as there is so much more choice. I like the shape of this one and it is ideal for the space I have on my desk. Regarding it's wifi capabilities, you have to place the dongle quite close to the keyboard, and I mean close.
Summary: Clever design, but too clever by half - it's awkward to type on. It now sits unused in a drawer, and I type on the laptop keyboard. What's the point of a keyboard that looks great but isn't very usable?
Summary: This is a neat little unit and looks great but it is too small if you are using a keyboard a lot. The lack of the arrow keys is a bit annoying (it's all done on one key which moves 4 ways). The size end to end is 12 inches.
Summary: Based on ownership approaching 1 year : Pros - style, build quality, freedom, compact, nice tactile feel to the keys. Cons - batteries need changing every 3-6 months and it does very occasionally crash requiring a battery pull, volume keys have lag before they change, I've never been able to type as fast as I could on a standard keyboard, no number keypad makes input telephone numbers more time consuming.
Summary: So I purchased this keyboard based on the amazing reviews. However if you are used to a regular keyboard it will be a longer learning curve to adjust to this one. I'm not sure if its only because of the curvature that I cannot type really well. I type faster and more fluent on a regular rectangular keyboard. However I keep missing letters between words using this one.
Summary: This is a very nicely designed and built keyboard. The quality of it is obvious as soon as you handle it but beware. If you have big or even medium size hands this is not the keyboard for you. It's very hard to judge the size from the pictures but it's very small - about the size of a micro-keyboard. If you're used to a full-size keyboard this one may frustrate you.
