Glad to have you back, CAD! I wondered what happened to you!
Lenovo = IBM... IBM sold out their laptop division to them about a decade ago. "ThinkPads" are Lenovo now.
Those with Windoze newer than XP blues, the free application "Classic Shell" is very light weight (in terms of PC overhead) and can make Windows 8 look 99% like XP or 7. I just installed it on a new Dell with 8.1 on it last week and its flawless.
I'll also add that new Dell, which was a $500 bottom of he line unit, boots Windows to a fully usable state in 13 seconds from total power off. Windows 8 sucks but it's speed is amazing.
