Summary: I got this K820E beauty on sale for 14.99 to replace my crappy generic HP which connected via the outdated PS/2 input. It's been hard to adjust to a new keyboard (obviously) but I felt that this was a good purchase.
Pros: - Nice and quiet (for a rubber dome), - Sleek design, - 2nd function buttons on the F row allow for quick access of minor alterations (play music, volume control, etc), - Hand rest included and stands are durable
Cons: - Keys are not contoured and feel a bit spaced out (minor complaint), - Stands are not rubberized so it won't stay in place if you push it lightly
Summary: I am coming from a Microsoft Laser 7000 keyboard, which I used for 6 or 7 years. That particular keyboard has a wave to the keys that makes it a bit more comfortable to use, dedicated media keys, and indented keys.
Pros: Inexpensive, Not wireless, Slim, Quiet, Professional-looking, Media functions, Good quality construction, Spillproof, Easy to clean/hides dirt and debris
Cons: Difficult to get a good feel for touch typers, Not terribly ergonomic
Summary: I wanted a chicklet keyboard for work similar to my one at home. This Logitech k280e at $15 is great (also got free shipping too) and if I needed more of them I would have probably bought a bunch more. People at work liked it to when they tried it out.
Pros: Quiet, Chicklet design
Cons: Not backlit (not that I cared, but NCIX required at least 1 con)
Summary: this is a descent logitech keyboard, worth the price when on sale. Recommend to use it with a HTPC set up. It types accurately and is light in weight. However, it will be nicer to have a wireless feature built in as it does add the redundant wire into the configuration.
Summary: I got this because I was using a PS/2 Logitech Y-SU61 Value Keyboard and the keys were very loud -- plus PS/2 is getting old. This keyboard is an awesome replacement! Will take some time to get used to the key size differences though.
Pros: - Solid design and is quite thin, - Almost completely silent key presses, - Uses a function key similar to Notebook PCs(Key sequence such as FN + F2) rather then single key presses(Good to preventing accidental key presses.), - Comfortable & Flat design with a nice smooth curve to rest your hands...
Summary: Very happy with my purchase. This is an excellent keyboard so far and it's very easy to type with. Logitech makes quality keyboards. I own a Das Keyboard with blue switches and I actually prefer typing on this Logitech K280e keyboard. So much softer and easier to get the words down.
