The 4820T is one of four models in the TimelineX series Acer introduced in June, ranging from a 3-pound, 11.6-inch flyweight to a 5.5-pound, 15.6-inch desktop alternative. It measures 9.6 by 13.5 by 1 inches.
The model I tested had a 2.26GHz Intel Core i3-350M processor, Intel HD graphics, 4GB of DDR3 RAM, a 320GB hard drive, dual-layer DVD±RW burner, 802.11b/g/n Wi-Fi, and a six-cell battery.
Many of the features on the 4820T apply to all four TimelineX models; Windows 7 Home Premium, to start with. Ports include HDMI, for doing high definition on external displays; VGA; and Gigabit Ethernet. There's a 1.3-megapixel webcam and digital microphone, and a multi-gesture (two-finger scroll, pinch, rotate, and flip) touchpad with a scrolling strip at the right. The touchpad can, sensibly, be toggled off when you don't want to do things by accident. Either Dolby Home Theater v3 or Dolby Sound Room audio is standard.
There are actually four versions of the 4820T in Acer's catalog. If the dual-core, quad-thread Core i3 CPU isn't macho enough for you, an alternate configuration comes with a Core i5 processor and a 500GB hard drive, while corresponding 4820TG models replace the Intel processors' integrated graphics with AMD's ATI Mobility Radeon HD 5650 adapter. Configurable options include bumping RAM up to 8GB, a higher-capacity battery, and Bluetooth.

One of the ways around the issues of security and control that make some businesses wary of cloud computing is to build a private cloud -- one that remains within the corporate firewall and is wholly controlled internally. Private clouds also increase the agility of IT an organization's IT infrastructure and make it easier to roll out new technology projects.
