Believe it or not, I bought a Walmart computer that I use almost exclusively for programming. I bought it online and cost $200 including shipping. The brand name is Motile but I think it's also available from other dealers under other names. Besides Sentinel, it has several RT Systems programs on it. It's 2.4 GHz, has a 14" screen and I brought it up to 16 GB of ram. Believe it or not, it came with almost no bloatware. I added Open Office and virus software. I'm not sure how long the battery lasts but I've run it for almost 7 hours without charging. It may be the best $200 I've spent in a long time. It's a really great machine, especially for the price and it works great for programming radios.
