Good morning
You'll be thrilled with both.
I'm sure LifeSaver and FrameVue will work fine on the POS computer. However, is it logistically practical to do so? Most shops have the CMC away from public view, in the back room; while the POS is right at the design counter. It lets you work up prices, and tracks the balance of what folks owe, when they come back to pick up their work. You'll want it within arm's reach.
If you need another inexpensive machine for this, there's one for $459 that will meet the needs of the POS.

You'll also want a laser printer. The Brother HL-2040 light duty model is normally $119 but its $49 at Staples this week, after rebate.
Staples has the Brother HL-2040 Monochrome Laser Printer (20ppm, 2400x600dpi) for a low $49.99 after rebate. Free Shipping. Tax in most states.
...and 6 or 7 backup chips, depending how many days of the week you are open:
Buy.com has the Kingston 1GB Data Traveler USB 2.0 Flash Drive for a low $9.95. Free shipping. Tax in CA, MA, TN.
You can also tie both machines into the same internet feed, with use of a ROUTER. The Linksys WRT54g model is sufficient for frame shop use, and costs about $50. (It's almost always on sale) If you get one of these, just MAKE SURE you disable or secure the wireless transmitter within. (otherwise, the neighborhood can get in)
See the Hardware thread in the computer forum, for additional suggestions.
Good luck and congratulations on the new tools!
