Need a wireless printer that will work with XP and Vista and am looking at these two. Should be able to get them for $70 and $100 respectively on black friday. The C4795 uses HP60 cartridges and the CD055A uses HP 564 cartridges. Any opinion on which will last longer, be most cost effective for normal home use, especially ink usage? Any other pros or cons on these two models? I think the CD055A has better scanning and photo printing and that pushes me towards the CD055A model. Thanks,
