My portable keyboard : Logitech K810 Bluetooth Illuminated Keyboard

The Logitech K810 Bluetooth Illuminated Keyboard is slim enough to carry with you in a laptop bag or backpack, and it swaps from your tablet, to your laptop, and again to your smartphone with the press of a button. Intelligent backlighting and proximity-sensing Bluetooth management help extend battery life, and built-in Windows 8 controls make it perfect for use with Microsoft’s Surface RT tablet. It’s a smart keyboard, and in addition to being the best Windows 8 keyboard we’ve seen,

Hand-proximity sensing turns on the backlighting as your hands approach the keyboard, while ambient light sensing detects whether the backlight is needed or not. It also disengages Bluetooth when not in use, reconnecting it as your hands approach the keyboard.

The keyboard has a pretty good range. Bluetooth connectivity usually drops off around thirty feet, but even from forty feet away, the Bluetooth connection allowed me to type without losing connection. The K810 powers off of a rechargeable battery, which Logitech estimates will last nearly a month for the average typist. Recharging is done via USB cable, and you can continue typing while you do it.

All in all, the Logitech K810 Bluetooth Illuminated Keyboard is a stylish-looking mobile keyboard, but the collection of features sets it above the rest. Swappable Bluetooth makes it perfect for use with multiple devices, across multiple operating systems, and smart features like intelligent backlight, proximity triggered Bluetooth connectivity, and built-in Windows 8

My ASUS dsl-n55u , ADSL Modem Router

By the time pass,I have touch many network device in order to use it by my self,for my friend as well as my customer.Today i have one of my favourite adsl router to review to you,It is ASUS DSL-N55U

It makes a good start, and despite a reasonable price around 5000 baht, this ADSL2/2+ router has plenty of features. There’s dual-band, concurrent Wi-Fi, rated at 300Mbits/sec in each band; twin USB ports, each one capable of supporting either a printer or a hard disk drive; FTP server capabilities; four Gigabit Ethernet ports; a power switch on the rear; and three, high-gain antennae sticking out the back.

When you connect to the DSL-N55U’s web UI, it delivers class-leading usability. The first page helps you set up the ADSL connection. Once that’s done, there’s a wireless and security setup wizard to go through, and you finally land on the router’s dashboard page. This displays a network map, showing an at-a-glance view of the health of your internet connection, and the status of the wireless network. Click an item on the map and further information appears in a panel to the side.

With the ability to change basic settings in these panels, you’ll barely need to wander outside the UI’s main page for most changes. When you do, the router provides help by way of some simple wizards. We particularly like the AiDisk function, which allows you to share storage across the internet through Asus’ own DDNS service. Including account setup, we were able to share our connected disk via FTP in less than a minute.

The only significant features missing from the DSL-N55U are wireless repeating functions, and advanced parental controls. You can block keywords and URLs and restrict usage based on the time of day, but there’s no whitelist control, nor more powerful, category-based filtering.

However, I’m willing to set aside these concerns in light of the Asus’ excellent all-round performance. At close range, we measured an average file-transfer rate of 13.6MB/sec over 2.4GHz, and 16.5MB/sec over 5GHz. At long range, speed over 2.4GHz was an impressive 6.3MB/sec. And, again, the DSL-N55U impressed over 5GHz, gaining a steady rate of 3.1MB/sec. For range, it’s one of the best routers we’ve seen recently, and certainly up among the most consistent.

The Asus doesn’t only impress in the wireless department. It also excelled in our USB disk tests. In the former, it delivered an average transfer rate of 12.2MB/sec, again a superlative performance.

In short, the Asus DSL-N55U couples table-topping performance in all departments and a great range of features with supreme ease of use, and does it all for a modest price. There’s no other ADSL router we’ve seen that carries off that combination with such competent, all-round aplomb.
