Can an android tablet be booted from a usb port?

Q. I was wondering if I can run one of those light weight linux distro installed on a usb flash drive on one of those android tablets.
1) Is there a cheap tablet PC (under $200) that can be booted from a usb port?
3) Can I find a lightweight linux distro that has all the drivers for that tablet?
Thanks for replying.

A. First of all, Android is Linux. It's a custom Linux kernel with a special software layer on top. And the customizations to the kernel and the software layer sitting on top of it are pretty important for it to run on the rather specialized smartphone architecture.

Second, a kernel has to be compiled to run on a certain architecture. So you'd have to find a version of Linux compiled for an ARM processor. That's not much of a problem. Several distributions, including Ubuntu, have ARM kernels. But then you'd have to have kernel modules for the drivers of the smartphone hardware, which... isn't nearly as likely. And you'd probably need a specially-designed interface, since Gnome or KDE really wouldn't work on a 4-inch touchscreen. And all of that would also have to be specially compiled for the kernel. And that's before we start with the application software. And by the time you got all of that working... you'd essentially have Android.

And even if you could do all of that, you'd have to have some way of booting from the USB, which you can't since smartphone firmware boots the kernel directly, without any sort of bootloader like you have on a personal computer.

If you want Android to be more Linux-y -- whatever that means, since the Linux experience differs greatly based on the graphical interface (assuming you use one) -- you can install a terminal emulator and even the bash shell. If you play around with it a bit, you might be able to install some command-line Linux software. But even then, it wouldn't be terribly useful, given the limited ability to enter text on a smartphone.


What is the difference between the Android Tablets for $100 and the Ipads for $499?
Q. They have these Android Tablets on sale for Black Riday under $100 and my daughter has been asking for a Ipad which I can't afford, but the Android Tablet says that U can search the web,play music,videos,games etc.

A. There is some difference and usually apple products have or atleast the reputation of more polish to the product attention to detail compared to the droid brethren. This isn't to say Android Tabs are bad with lots of different tabs coming out and matching or beating the iPad in some or all areas and constantly improving software. It is just you would need to check specs and state which android tabs your looking at as some are not up to scratch compared to the iPad.
As far as similar spec SONY S, Galaxy Tab 10.1, ASUS Eee Pad, MOTOROLA Xoom, HTC Flyer, LG Optimus Pad are all very familiar to the iPad but not one and have all the features.
And if worse comes to worse you could always find student friend and get a lovely 14% discount >_>


What is a good android tablet that is cheap?
Q. I am looking at getting an android tablet but i would like to spend $300 or less. There are a lot on eBay and i was wondering what some good ones are. I have been looking at the galaxy tabs and i really like them but they are $300 or more. I am looking for one with a 7 inch screen not the big 10 inch ones.
Thanks for any advice!

A. Hi friend,
I think the new one 7inch GT-Pad android 2.3 OS tablet PC is good one. run smoothly and capacitive multi-touch. Flash 10.2 will let you see the movie youtube online. it will bring you more better user exprience.

What art programs can you use on an Android Tablet?
Q. I just got an android tablet and wanted to start doing a little more art like drawing and stuff and was wondering if I could download something like GIMP,PSE, ect.

A. You cant use GIMP and Photoshop Elements in Android tablets. You can only use them on Macs, Windows, and (for GIMP only) on Linux operating systems.
