My mini 10v has been going strong for several years. I used to run Snow Leopard, but got tired of that and eventually returned to linux (currently Xubuntu). I’ve needed to make a few upgrades along the way to keep up with the times. Here are my suggestions if you want to pimp your mini 10v
1) Upgrade to 2GB of RAM. There is only one slot for a ram card and you can only max it out at 2Gbytes.
2) Install a SSD – these have come way down in price. The boot performance will knock your socks off. Make sure you get a 2.5 inch drive so it fits in your mini. The one below is what I would buy.
3) Get the high capacity battery – 6 cell. I get about 5 hours on my laptop with this battery.
