Ok... this may come out crass - but - How did you post this question if you didn't have access to a PC, Laptop or Smartphone?
No, no - not tryen to throw punches. I mean:
1 - Nowadays, schools colleges and businesses sometimes liquidate older systems when they upgrade. It's just a matter of contacting and finding out when the Secret Sales happen.
2 - Local Libraries have PC's you can use for Free. Get yourself a Yahoo / Hotmail (free) Email account and viola!
3 - Smartphone. Today's cellphones (smartphone / quick messaging) phones give you access to Social Media like Facebook, Twitter and Hubpages (for me). Even better - you don't need a Contract - Prepaid Service works well.
Now - if it's 'to keep in touch with family' you don't need the latest and greatest - and in fact, don't really need a PC/Laptop at all.
If you plan on using it for school - you don't need the latest and greatest.
If you just want it for the sake of getting it for Free - you're gonna miss the sympathy target from me. I've used the Library PC's. No Shame in My Game.
Not being mean, I got my new laptop during Tax Season. It don't have to be a $1500 laptop to open an Internet Browser.
