definitely i use a mouse for doing work in sql server/excel/coding/xmlspy/edinotepad i can't get the copy paste resolution that i can with a mouse. but for surfing love it.
i paid $38 at cowboom for mine. there's about 3 or 4 of them around here. guess alot of folks returned them and they had a blowout on open box product. all were perfect minus 2 batteries. is there a place to get them cheaper?
Are you using menus for Copy/Paste? Does CTRL/CMD+C/V not work?
Also, are you saying that you got the Magic Trackpad for $38? Guh... lucky... /napoleon dynamite
