It seems like every day brings the announcement of a new mini-laptop from a major computer maker. Many of these new models are priced at $400 or less, but some manufacturers seem determined to push the boundaries of netbooks with $500 and $600 models with premium features like high resolution displays, optical disc drives, and touchscreens.

But over the past 18 months or so the market for low cost ultraportable laptops has fleshed out nicely and there are now a whole lot of models available at very reasonable prices. A few months back I put together a list of 13 netbooks for $399 or less. Today I present an updated list of 19 netbooks for $350 or less.

All of the netbooks listed below come with 1.6GHz Intel Atom processors unless otherwise stated. I just figured I’d write that here and save myself some time writing it over and over. All of the netbooks in this list have 9 or 10 inch displays. I opted to leave out models with 7 inch screens, but if you hunt around for older Asus Eee PC 701 models or newer Xburst netbooks you can often find these mini-netbooks for under $200.

10 inch laptops

• Lenovo IdeaPad S10 – $349: This netbook has a 10.2 inch display, a reasonably sized keyboard, an 80GB hard drive and an ExpressCard slot. At this price point you get 512MB of RAM, and a 3 cell battery.
• Asus Eee PC 1000HA – $349.99:This netbook is much like the popular Asus Eee PC 1000H. Both have 1G of RAM, 160GB hard drives, and 6 cell batteries. The main difference is that the 1000HA does not have built in support for Bluetooth or 802.11draft-n wireless networking.
• Acer Aspire One AOD150 – $349: This is Acer’s first netbook with a 10 inch display. It features the same keyboard as the original 8.9 inch version, but a slightly larger touchpad, better battery performance, and a larger screen (with the same 1024 x 600 pixel resolution as the original). Also available in black, red, and white.
• HP Mini 1000 Mi Edition (Linux) – $319.99: The base configuration of this Linux netbook comes with an 8.9 inch display, but you can opt for a 10.1 inch, 1024 x 576 pixel screen for an extra $40, which brings the price to just under $320.
• MSI Wind U100 (with 3 cell battery) – $299: This netbook comes with a 160GB hard drive, 1GB of RAM, and a 3 cell battery. It’s popular with folks who like to install OS X on netbooks thanks to excellent hardware support.
• MSI Wind U120 – $329.99:The Wind U120 is similar to the Wind U100 in that it has a 160GB hard drive, 1GB of RAM, and runs Windows XP Home Edition. But this netbook sports a redesigned chassis and comes with a 6 cell battery. Unfortunately, while the U100 lets users upgrade the RAM to 2GB, the U120 tops out at 1GB.
• MSI Wind U100 (with 6 cell battery, pink) – $349.99: This model is similar to the Wind U100 with a 3 cell battery listed above, but it comes with a higher capacity 6 cell battery that runs for at least twice as long. The only color available for under $350 at the moment is pink, but if you keep an eye on the prices you’ll see black and white models at similar prices from time to time.

9 inch laptops

• HP Mini 1000 – $298.97: This netbook is available with several screen, memory, and storage configurations. This particular model comes with an 8.9 inch display, 512MB of RAM, and an 8GB solid state disk. It runs Windows XP, and despite the smaller screen, shares the same excellent keyboard as the 10.1 inch version.
• HP Mini 1000 Mi Edition (Linux) – $279.99: This netbook runs HP’s custom version of Ubuntu 8.04.1 Linux. The base model has an 8GB solid state disk, 512MB of RAM, and an 8.9 inch display. You can upgrade the storage, memory, and screen size for additional fees.
• Acer Aspire One (with 8GB SSD and Windows XP) – $239: There are several Aspire one models with 8.9 inch displays selling for under $350. They all support up to 1.5GB of RAM, but come with a variety of storage, memory, and operating system configurations. This is one of the cheapest at the moment. It comes with an 8GB solid state disk (plus an 8GB SD card), 1GB of RAM, and runs Windows XP Home. It has a 3 cell battery.
• Acer Aspire One (with 8GB SSD and Linux): – $273.28: This model is similar to the one listed above, but it comes with 1GB of RAM and runs Linpux Linux Lite.
• Acer Aspire One (with 160GB HDD, 3 cell battery) – $300: This model comes with a 160GB hard drive, 1GB of RAM, and Windows XP. It has a 3 cell battery.
• Acer Aspire One (with 160GB HDD, 6 cell battery) – $330: This Aspire One model is almost identical to the one above, but it comes with a higher capacity 6 cell battery which should provide twice the run time.
• Dell Inspiron Mini 9n – $249: This is Dell’s first entry into the netbook space. The base model ships with an 8GB solid state disk, 512MB or RAM and Ubuntu 8.04.1 Linux. You can upgrade the storage and memory options, but that will increase the price.
• Dell Inspiron Mini 9 – $299: Like the version listed above, this model comes with an 8GB SSD and 512MB of RAM. But it runs Windows XP.
• Asus Eee PC 900 (refurbished) – $180: This may be an older model with a 900MHz Intel Celeron processor, 512MB of RAM, and 4GB solid state disk instead of a larger hard drive or SSD. But it’s hard to argue with the price. If you’re not satisfied with refurbished products, you an also pick up a new model for as low as $253. But at that price, I’d recommend checking out the Eee PC 901.
• Asus Eee PC 901 – $279.99: This netbook ships with a 12GB solid state disk, 1GB of RAM, 6 cell battery, and runs Windows XP Home Edition. It’s also available for the same price with a 20GB SSD and Linux.
• Asus Eee PC 900HA – $293.99: The Asus Eee PC 900HA has an Intel Atom processor, but the same chassis as the Eee PC 900. It also has 1GB of RAM and a roomy 160GB hard drive.
• Asus Eee PC 904HA – $308.40: Want a laptop with a large keyboard like you’d find on a 10 inch netbook, but with at the low price of an 8.9 inch model? The Asus Eee PC 904HA has an 8.9 inch display with a large bezel around it. The chassis is pretty much the same one used in the larger Eee PC 1000H, which means that you get a larger, easier to use keyboard. You also get 1GB of RAM, a 160Gb hard drive, a 6 cell battery, and 802.11b/g WiFi networking.
