Higher end models were released in June 2010 consisting of the AMD Athlon II Neo processor and ATI Radeon HD 4225 graphics controller.

[5] Also released was a version of the Aspire One 521 with an AMD V105 processor running at 1.2 GHz, an ATI Radeon 4225 graphics controller, and equipped with a HDMI port.

Models with names starting in L, or ending in A followed by a letter for color, are shipped with Linpus Linux Lite, which is based on Fedora 8.

The default desktop environment has been designed to hide advanced features from the user and to prevent modification.

It is possible to modify the system to present a more traditional Xfce 4 desktop, enable more advanced features such as context menus, or install additional software.

OpenBSD releases ranging from 4.4 to 6.4 are known to run on some of the many models of Aspire One,[28] with some limitations based on BIOS and other variations.

Some peripherals, like a USB mouse or Ethernet port, will not be detected by the standard setup and may require manual tweaking.

The Intel Atom platform has a specified maximum TDP of 11.8 W. Individual figures are 2.5 W for the N270 processor, 6 W for the 945GSE chipset and 3.3 W for the 82801GBM I/O controller.

Battery life is shorter on HDD configurations with Windows XP, at approximately 2.5 hours for the three cell.

[33] Installing memory modules larger than 2 GB has caused the Aspire to fail the power-on self-test.

Full volume MP3/audio playback easily causes these models to run extremely slowly, or crash because of unresponsive disk I/O.

This problem also causes bad sectors, crashed hard drives and corrupt Windows partitions in the long term.

Workarounds identified are: listening to music at a lower volume, using only the left speaker, using a software equalizer to tone down the 1 kHz frequency, replacing the hard drive with an SSD, and trying to install soft sound dampening material around the speakers and the hard drive.

[61][62][63][64] The Acer Aspire One Happy is a 10.1 inch netbook with different operating systems: (Android 2.1 and Windows 7).

There is also a 3G version for proper portability, with each model measuring 24 mm thick and weighing 1.25 kg with a six-cell battery pack.

[68] The AOD270-1410, the black model, features a 10.1 inch WSVGA LED-backlit display with CrystalBrite technology with a 17:10 aspect ratio and 1024 x 600 resolution display, 1 GB DDR3 SDRAM memory, a 320 GB 5400 rpm hard drive and integrated Intel GMA 3600 graphics with 64 MB dedicated memory.

Some models of the Acer Aspire One D270 have Windows 7 Home Basic pre-installed and have an Intel Atom N2800 1.86 GHz processor.

It is believed that many other inexpensive VT64x equipped DDR3 netbooks have the same capability but disabled for licensing reasons or due to the clock circuitry being unable to handle certain modules correctly resulting in system instability, that can be overcome using spdtool and slightly altering timing parameters.

Further investigation suggests that the issue may be BIOS corruption and replacing or reflashing the chip may well resolve it but as of yet this is untested.

CNET editors' review has been positive,[70][71] although held reservations as the Aspire One is early to market and many netbooks are planned for the near future.

A The Tech Report (Techreport.com) review of the 751h, and the similar Gateway LT3103U, was generally positive, praising the notebooks' battery life but criticizing the large number of third-party software products preinstalled and running by default on the computers.
