Hi Moish. I realise you asked this question several years ago and you probably don't even use the Mini 10 anymore, but I thought I would answer, in case anyone else has one lying around.
I have found the mini 10 to be a robust and reliable machine. I bought mine in 2010, refurbished, from Dell and have only had to replace the battery: I bought a six cell one two years ago which has proved to be excellent, and it only cost me £40 (maybe $55).
It is not a speed machine. It has an old-style Atom processor and on-board graphics and, while it was okay with Windows XP, it never really worked with W7. Instead, I have used a variety of Linux OSs, settling upon [http://lubuntu.net/|Lubuntu]. Everything works (you need an ethernet connection for the installation as you have to download and activate the WiFi driver after installing the OS) and it is a remarkably efficient writing and browsing machine. It boots in under a minute and the screen still looks amazingly good: one of the advantages of an old-style TFT screen. I'm not crazy about the touchpad, but, for its size, the keyboard is superb. With LibreOffice Writer, a cloud storage service (I use [https://mega.nz/|MegaSync]) and a light web browser ([https://mega.nz/|Midori]'s good), it is still a useful and easy-to-transport machine. It doesn't have Bluetooth, but I carry a nice pair of headphones with me anyway, and have my music in high-quality FLAC files, so I don't have a problem with that.
I reckon that, by keeping this machine going, I have saved myself thousands of pounds as well as reducing my environmental impact. I backup everything on it, because a seven-year-old hard drive isn't going to last for ever, but I am hoping that when it does give up, I can replace it with an SSD.
Best wishes
