My VAOI - VGC-V520G is only two years old. Decent configuration:
Pentium 4 CPU 3.2 GHz HT
1 Gig main memory
250 Gigs hard drive
TV Tuner
NVIDIA GeForce FX Go5700 Video Card
Not too shabby for an old PC
Well ... not good enough for Vista Ultimate (Sony later told me - should of checked before I purchased - that it is just rated for Vista Baisc!!)
When I loaded it ... the nice Vista "eye candy" Aero Glass was not available ... only basic. The TV Tuner was gone! I had to fight to get NVIDIA drivers going. And Windows Media Player didn't play much media properly (Video - no audio.) SONY doesn't do much for old models in terms of compatability.
But the WORSE ... Vista is a DISK PIG!! Here's what happens ... say you have a number of games installed ... the big kind (e.g., Oblivion, NeverwinterNights, etc.) They might take up say ... 30 gigs of storage. No big deal for a 250gig Harddrive. Well ... a feature of VISTA ... to protect you ... is to establish 'virtual' copies of all 'old' programs for each user. The problem is that it makes ACTUAL copies of the data sources. So ... perhaps 25 of the 30gig copies for EACH user!!! Vista doesn't ask you if you want this done (at least I don't remember seeing it ask me!) ... it just does it!
Well last night I ripped Vista off ... restored an OLD version of Windows XP. Started at 8:30pm ... finished most stuff (with NO game program reinstalls) by 6:30am. I probably had over 120 PATCHES to apply!!!!
But I'm baaaacccckkkk!!!! TV Tuner works ... storage is low ... performance is great! I LIKE Windows XP!!!
What are YOUR Vista horror stories!!

[BTW, yeah ... I know ... should of backup up before I changed!!!
