Computer Replacement

Because of health issues, what I do has had to look different and writing is a big part of this.  But my computer is starting to show signs of impending doom (it's rather old for a computer).  It is a (very heavy) desktop and I literally carry it in a huge suitcase strapped to my back everywhere I go--to the library, travel, etc... (it's embarrassing).   I am looking to buy a new laptop before as going with an older one always sets you back in technology land.  They are $2000 for an Apple 15 inch.   If you would like to be a part of this I would be grateful.  Thank you and blessings!
